Description:
Precipitation and throughfall samples were collected over a period of 4 years (1 January 1996-31 December 1999) at three different sites in Poland: one on moraine hills, one in the lowlands and one in a mountainous region. The aim of this project was to study the chemical composition of the samples, ionic correlations and fluctuations of selected variables with time in relation to geographical location, type of tree cover and climatic conditions. The samples were characterized by determining the values of pH, electrolytic conductivity and concentrations levels of SO"4^2^-, NO"3^-, Cl^-, Ca^2^+, K^+, Na^+ and Mg^2^+. Statistical analysis revealed significant differences between the results obtained for different sampling site locations and characteristics (region of Poland, open area vs. throughfall) in four cases. The results obtained for precipitation samples were similar to those for throughfall samples only for acidic anions (SO"4^2^- and Cl^-). For open areas, pH fluctuations were observed in 12-month cycles. Differences between the concentration levels of ions in the samples from the three sites could be explained by different amounts of precipitation at these sites. Concentrations of ions in precipitation and throughfall samples followed similar trends, the concentration levels being dependent on the kind of trees in the area, their age, and acidity of the precipitation. Significant differences were found for the concentration factors of the individual ions in throughfall between the sampling sites. Ionic correlations were examined to determine which salts contributed to the observed ion levels.

Description:
The general approach to the detailed characterizing of peak properties based on the use of characteristic points on a peak contour located at the certain levels is proposed. Three basic functions of peaks have been chosen which are submitted in normalized form on height and width. The ability to characterize a peaks shape of a certain analytical series is shown by an example of series of analytical peaks of thallium obtained by stripping voltammetry at linear and step potential sweep. Also the proposed shape parameters are studied for groups of stripping voltammetry and chromatographic peaks.

Description:
The penicillin-binding protein PBP 2x^* from Streptococcus pneumoniae has been utilised to develop a novel microplate assay for the detection and determination of penicillins and cephalosporins with intact beta-lactam structure in milk, bovine and porcine muscle juice, honey and egg. In the assay, the receptor protein is immobilised to a microplate in the first step. To each sample a bifunctional reagent is added, with ampicillin and digoxigenin as functional groups (DIG-AMPI). The amount of bifunctional reagent, which is bound via its ampicillin part to the receptor protein, decreases with increasing beta-lactam concentration in the sample. The detection step uses anti-digoxigenin F"a"b fragments marked with horseradish peroxidase. The more bifunctional reagent is bound to the receptor protein, the more antibody fragments are bound via the digoxigenin part of the reagent. A maximum colour development with tetramethylbenzidine as chromogen for the peroxidase reaction is achieved, when no beta-lactam residues are present. A fractional factorial design was applied to detect chemometrically effects and interactions of the assay parameters. For optimisation of the significant parameters a Box-Behnken design was used. The assay has been developed for various food matrices as screening test with the option for a quantitative assay, when the identity of the residual beta-lactam is known (e.g. elimination studies). Cefoperazon, cefquinome, cefazolin, cloxacillin, ampicillin and benzylpenicillin could be detected at levels corresponding to 1/2EU maximum residue limit (MRL) in milk, meat juice from muscle tissue of different species, egg and honey (where applicable) without needing lengthy and elaborate sample pre-treatment. Matrix calibration curves are presented, which show that quantitative analyses are possible.

Description:
The study presents the application of selected chemometric techniques: cluster analysis, principal component analysis, factor analysis and discriminant analysis, to classify a river water quality and evaluation of the pollution data. Seventeen stations, monitored for 16 physical and chemical parameters in 4 seasons during the period 1999-2003, located at the Bagmati river basin in Kathmandu Valley, Nepal were selected for the purpose of this study. The results allowed, determining natural clusters of monitoring stations with similar pollution characteristics and identifying main discriminant variables that are important for regional water quality variation and possible pollution sources affecting the river water quality. The analysis enabled to group 17 monitoring sites into 3 regions with 5 major discriminating variables: EC, DO, CL, NO"2N and BOD. Results revealed that some locations were under the high influence of municipal contamination and some others under the influence of minerals. This study demonstrated that chemometric method is effective for river water classification, and for rapid assessment of water qualities, using the representative sites; it could serve to optimize cost and time without losing any significance of the outcome.

Description:
Watermilfoil genus Myriophyllum could be used in ecological surveys as in-situ biomonitors of metal pollution and water quality due to its ability to accumulate chemicals. The copper and cadmium sorption characteristics of Myriophyllum alterniflorum have been investigated. The Langmuir and Freundlich isotherms were used to model the metal sorption isotherms and the monolayer sorption capacities, as obtained by the Langmuir isotherm, were determined to be 13.9 mg/g and 11.1 mg/g for Cu^2^+ and Cd^2^+ respectively. Results have been compared with previous works on watermilfoils and are in accordance with those obtained on Myriophyllum spicatum. The sorption of the two metals was time-dependent and the kinetics fitted the pseudo-second-order equation well. The data were discussed in terms of ionic radii and HSAB concept. The phytotoxic effects assessed by classical (i.e. changes in biomass, node length) and photosynthetic pigments content endpoints have been investigated using chemometric techniques leading to an effect of cadmium onto photosynthetic pigments.

Description:
The H-Sensor reported herein is a micro-fluidic device compatible with flow injection analysis (FIA) and high performance liquid chromatography (HPLC). The device detects analytes at two separate off-chip absorbance flow cells, providing two simultaneous absorbance measurements. The ratio of these two absorbance signals contains analyte diffusion coefficient information. A theoretical model for the sensing mechanism is presented. The model relates the signal Ratio to analyte diffusion coefficient. The model is qualitatively evaluated by comparing theoretical and experimental signal Ratio values. Experimental signal Ratios were collected via FIA for a variety of analytes, including sodium azide, benzoic acid, amino acids, peptides, and proteins. Measuring absorbance at multiple wavelengths provides higher order data allowing the analyte signals from mixtures to be deconvolved via classical least squares (CLS). As a result of the H-Sensor providing two simultaneous signals as a function of time for each sample injection, two simulated second-order HPLC chromatograms were generated using experimental H-Sensor data. The chemometric deconvolution method referred to as the generalized rank annihilation method (GRAM) was used to demonstrate chromatographic and spectroscopic deconvolution. GRAM also provides the signal Ratio value, therefore simultaneously obtaining the analyte diffusion coefficient information during deconvolution. The two chromatograms successfully serve as the standard and unknown for the GRAM deconvolution. GRAM was evaluated on chromatograms at various chromatographic resolutions. GRAM was found to function to a chromatographic resolution at and above 0.25 with a percent quantitative error of less then 10%.

Chemometric Techniques for Quantitative Analysis

Most ideal tutorial of chemometrics
Chemometrics is not intrisically difficult to understand, but it has a high barrier especially for beginners. One of the reasons may be that most of tutorials employses unnecessarily many equations, and they describe claculation algorithms too much. Nonetheless, the basic concept of PCR and PLS should be described on the line of CLS and ILS. The discovery of advantage of ILS, and the idea of using latent variables by PCA are the most important to fully understand PCR and PLS. Richard Kramer writes the book along this concept, and we can comprehensively understand the ideas of maltivariate analysis of spectra. He uses many figures, as if we were performing simulations by ourself. After fully understanding of this book, we would understand other tutorials more deeply and easily.

Basic Chemometric Techniques in Atomic Spectroscopy (RSC Analytical Spectroscopy Monographs) Description

This is the first book for atomic spectroscopists to present the basic principles of experimental designs, optimization and multivariate regression. Multivariate regression is a valuable statistical method for handling complex problems (such as spectral and chemical interferences) which arise during atomic spectrometry. However, the technique is underused as most spectroscopists do not have time to study the often complex literature on the subject. This practical introduction uses conceptual explanations and worked examples to give readers a clear understanding of the technique. Mathematics is kept to a minimum but, when required, is kept at a basic level. Practical considerations, interpretations and troubleshooting are emphasized and literature surveys are included to guide the reader to further work. The same dataset is used for all chapters dealing with calibration to demonstrate the differences between the different methodologies. Readers will learn how to handle spectral and chemical interferences in atomic spectrometry in a new, more efficient and cost-effective way.

Quality Assurance in the Analytical Chemistry Laboratory Description

Analytical chemical results touch everyones lives can we eat the food? do I have a disease? did the defendant leave his DNA at the crime scene? should I invest in that gold mine? When a chemist measures something how do we know that the result is appropriate? What is fit for purpose in the context of analytical chemistry? Many manufacturing and service companies have embraced traditional statistical approaches to quality assurance, and these have been adopted by analytical chemistry laboratories. However the right chemical answer is never known, so there is not a direct parallel with the manufacture of ball bearings which can be measured and assessed. The customer of the analytical services relies on the quality assurance and quality control procedures adopted by the laboratory. It is the totality of the QA effort, perhaps first brought together in this text, that gives the customer confidence in the result. QA in the Analytical Chemistry Laboratory takes the reader through all aspects of QA, from the statistical basics and quality control tools to becoming accredited to international standards. The latest understanding of concepts such as measurement uncertainty and metrological traceability are explained for a working chemist or her client. How to design experiments to optimize an analytical process is included, together with the necessary statistics to analyze the results. All numerical manipulation and examples are given as Microsoft Excel spreadsheets that can be implemented on any personal computer. Different kinds of interlaboratory studies are explained, and how a laboratory is judged in proficiency testing schemes is described. Accreditation to ISO 17025 or OECD GLP is nearly obligatory for laboratories of any pretension to quality. Here the reader will find an introduction to the requirements and philosophy of accreditation. Whether completing a degree course in chemistry or working in a busy analytical laboratory, this book is a single source for an introduction into quality assurance.

Description:
A newly developed quantitative near-infrared spectroscopy (NIRS) system was used to measure changes in cortical hemoglobin oxygenation during the Verbal Fluency Task in 32 healthy controls, 15 subjects with mild cognitive impairment (MCI), and 15 patients with Alzheimer's disease (AD). The amplitude of changes in the waveform, which was quantitatively calculated by a signal processing method, was significantly lower in the frontal, and the bilateral parietal areas in the AD group, whereas that in the MCI group was significantly lower only in the right parietal area. The NIRS system may be a potential tool for the primary screening of AD.

Description:
Owners of homes with pitched roofs visible from ground level often prefer non-white roofing products for aesthetic considerations. Non-white, near-infrared-reflective architectural coatings can be applied in situ to pitched concrete or clay tile roofs to reduce tile temperature, building heat gain, and cooling power demand, while simultaneously improving the roof's appearance. Scale-model measurements of building temperature and heat-flux were combined with solar and cooling energy use data to estimate the effects of such cool-roof coatings in various California climates. Under typical conditions-e.g., 1kWm^-^2 summer afternoon insolation, R-11 attic insulation, no radiant barrier, and a 0.3 reduction in solar absorptance-absolute reductions in roof surface temperature, attic air temperature, and ceiling heat-flux are about 12, 6.2K, and 3.7Wm^-^2, respectively. For a typical 1500ft^2(139m^2) house with R-11 attic insulation and no radiant barrier, reducing roof absorptance by 0.3 yields whole-house peak power savings of 230W in Fresno, 210W in San Bernardino, and 210W in San Diego. The corresponding absolute and fractional cooling energy savings are 92kWhyr^-^1 (5%), 67kWhyr^-^1 (6%), and 8kWhyr^-^1 (1%), respectively. These savings are about half those previously reported for houses with non-tile roofs. With these assumptions, the statewide peak cooling power and annual cooling energy reductions would be 240MW and 63GWhyr^-^1, respectively. Statewide energy savings would reduce annual emissions from California power plants by 35kton CO"2, 1.1ton NO"x, and 0.86ton SO"x. The economic value of cooling energy savings is well below the cost of coating a tile roof, but the simple payback times for using cool pigments in a roof tile coating are modest (5-7yr) in the warm climates of Fresno and San Bernardino.

Description:
Visual feedback of hand movement is crucial to accurate reaching. Although previous studies have extensively examined spatial alteration of visual feedback (e.g., prism adaptation), temporal delay of visual feedback has been less explored. In the present study, we investigated the effect of delayed visual feedback of the moving hand in a reaching task. The prefrontal cortical activity was measured by near-infrared spectroscopy (NIRS). Twelve subjects performed reaching tasks under two conditions where visual feedback of their own hand was delayed by 200 ms (delay condition) or 0 ms (normal condition). Introducing the visual feedback delay significantly disrupted the reaching performance, although the subjects gradually adapted to the delay during the experiment. There was a clear tendency to overreach the target in the delay condition, even after the reaching movement had been practiced sufficiently in the normal condition. We observed marked oxy- and total-Hb decreases in the dorsal prefrontal area in the delay conditions. The decrease began shortly after task onset and diminished during the rest period, indicating that the decrease was task-induced. Furthermore, the oxy- and total-Hb decreases were significantly correlated with task performance-the degree of decrease was larger as the subject made more errors. We suggest that the decreases in oxy- and total-Hb at the dorsal prefrontal area are related with the visuomotor recalibration process.

Description:
Multi-channel near-infrared spectroscopy (NIRS) is a relatively new method to investigate the brain activation, based on changes in oxygenated haemoglobin (O"2Hb) and deoxygenated haemoglobin (HHb). Recently, it has been shown that NIRS seems to be able to detect even small changes in O"2Hb and HHb concentration due to cognitive demands. This study aimed at investigating the changes in O"2Hb and HHb concentrations of the parietal cortex during a spatial task, a modified version of the Benton Line Orientation Task [Gur, R. C., Alsop, D., Glahn, D., Petty, R., Swanson, C. L., Maldjian, J. A., et al. (2000). An fMRI study of sex differences in regional activation to a verbal and a spatial task. Brain & Language, 74(2), 157-170.]. Twenty-four subjects were measured with NIRS while they had to estimate the orientation of a given line or to name the colour of the line in the control condition. Both conditions consisted of three activation phases each lasting 30s, with a 10s baseline and a 20s post resting period. For assessing the changes in O"2Hb and HHb concentrations, we measured with 24 NIRS channels over the parietal cortex using the NIRS apparatus ETG-100 (Hitachi Medical Ltd.). O"2Hb concentration significantly increased during the active phase compared to the baseline for both conditions, but was significantly higher in the active phase for the line orientation condition compared to the colour naming condition bilaterally parieto-occipital. For the HHb concentrations, we only found significant decreases for both conditions but no differences between the conditions. The results of our study underscore the value of multi-channel NIRS for assessing cortical activation during cognitive tasks.

Description:
Bio-optical algorithms for remote estimation of chlorophyll-a concentration (Chl) in case-1 waters exploit the upwelling radiation in the blue and green spectral regions. In turbid productive waters other constituents, that vary independently of Chl, absorb and scatter light in these spectral regions. As a consequence, the accurate estimation of Chl in turbid productive waters has so far not been feasible from satellite sensors. The main purpose of this study was to evaluate the extent to which near-infrared (NIR) to red reflectance ratios could be applied to the Sea Wide Field-of-View Sensor (SeaWiFS) and the Moderate Imaging Spectrometer (MODIS) to estimate Chl in productive turbid waters. To achieve this objective, remote-sensing reflectance spectra and relevant water constituents were collected in 251 stations over lakes and reservoirs with a wide variability in optical parameters (i.e. 4@?Chl@?240 mg m^-^3; 18@?Secchi disk depth@?308 cm). SeaWiFS and MODIS NIR and red reflectances were simulated by using the in-situ hyperspectral data. The proposed algorithms predicted Chl with a relative random uncertainty of approximately 28% (average bias between -1% and -4%). The effects of reflectance uncertainties on the predicted Chl were also analyzed. It was found that, for realistic ranges of R"r"s uncertainties, Chl could be estimated with a precision better than 40% and an accuracy better than +/-35%. These findings imply that, provided that an atmospheric correction scheme specific for the red-NIR spectral region is available, the extensive database of SeaWiFS and MODIS images could be used to quantitatively monitor Chl in turbid productive waters.

Description:
It has been suggested that frontal brain asymmetry is associated with differences in basic emotional dimensions, particularly in activation of systems underlying avoidance-withdrawal behavior. We examined regional cerebral oxygenated hemoglobin (O"2Hb) levels in human medial prefrontal cortex (MPFC) using near-infrared reflection spectroscopy (NIRS) prior to and during anticipatory anxiety to determine if NIRS could detect any anxiety-related changes. Transient anxiety was induced in 56 normal volunteers by anticipation and a painful shock to the right-hand's median nerve. Pre- and post-anxiety affective statuses were measured using the State-Trait Anxiety Inventory (STAI) and Temperature Character Inventory (TCI). NIRS recorded from the left and right frontal brain regions. Right MPFC O"2Hb was significantly increased relative to left MPFC O"2Hb during anticipation of the shock. Right-sided O"2Hb increases were significantly correlated with the TCI Harm Avoidance subscale. These results support the hypothesis that O"2Hb levels in the right frontal region correlate with anxiety or heightened negative affect.

Chemometrics: A Practical Guide (Wiley-Interscience Series on Laboratory Automation)

Chemometrics for the near-beginner
The authors have put together a supremely useful guide to actually using chemometric techniques, as opposed to academic research. Consequently, my copy is getting dog-eared from frequent use. Perhaps the most helpful part of the book is the multitude of tables that explain when each different technique might best be used, and how to understand and interpret the diagnostics that arise from the calculations. The table of questions to ask BEFORE an experiment is worth the price of the book. If you're trying to write new chemometric algorithms, buy something else. But if you're trying to apply chemometric techniques in the 'real world' with the highest information-to-effort ratio, you need a copy of this book.

A "Users Guide" to chemometrics
Chemometrics by Beebe et al. is my first recommendation to colleagues interested in the successful use and theory of chemometrics. It is a user focused book with theory sufficient to guide the appropriate and informed use of chemometric techniques in a variety of analyses. It is a "hard read" in the best sense of that phrase. You will probably have to work at getting through this book, but you do not need a degree in mathematics to understand and enjoy it.

If you are using one of the many "shrink wrapped" chemometrics software packages available today, and you are troubled by these techniques great utility, and your limited understanding of the underlying theory, Beebe is a great a place to start.

Solid, well written book
Admittedly, I'm biased as the authors are friends. However, this is one of the best books on chemometrics, particularly for those who have some exposure to the subject and wish to learn more. The authors have drawn on their years of experience explaining complex results to non-expert clients to present some complex mathematical ideas in an understandable fashion.

Chemometrics for Pattern Recognition Description

Over the past decade, pattern recognition has been one of the fastest growth points in chemometrics. This has been catalysed by the increase in capabilities of automated instruments such as LCMS, GCMS, and NMR, to name a few, to obtain large quantities of data, and, in parallel, the significant growth in applications especially in biomedical analytical chemical measurements of extracts from humans and animals, together with the increased capabilities of desktop computing. The interpretation of such multivariate datasets has required the application and development of new chemometric techniques such as pattern recognition, the focus of this work.

Included within the text are:

• ‘Real world’ pattern recognition case studies from a wide variety of sources including biology, medicine, materials, pharmaceuticals, food, forensics and environmental science;
• Discussions of methods, many of which are also common in biology, biological analytical chemistry and machine learning;
• Common tools such as Partial Least Squares and Principal Components Analysis, as well as those that are rarely used in chemometrics such as Self Organising Maps and Support Vector Machines;
• Representation in full colour;
• Validation of models and hypothesis testing, and the underlying motivation of the methods, including how to avoid some common pitfalls.

Relevant to active chemometricians and analytical scientists in industry, academia and government establishments as well as those involved in applying statistics and computational pattern recognition.

Analytical Chemistry: Theoretical and Metrological Fundamentals Description

Fundamentals of Analytical Chemistry are usually presented as a sum of chemical and physical foundations, laws, axioms and equations for analytical methods and procedures. In contrast, this book delivers a practice-oriented, general guiding theory valid for all methods and techniques. Starting with a closer look to analytical signals and their dependencies, all the important figures of merit characterizing the power of analytical procedures and the reliability of analytical results are discussed and quantified, such as sensitivity, precision, accuracy and ruggedness. Elements of signal theory, information theory, statistics and fundamentals of calibration are also presented for this aim. The metrological foundations included define strictly the figures of merit in order to minimize confusions still appearing in Analytical Chemistry publications today.

Fault Detection and Diagnosis in Industrial Systems

Chemometrics: Statistics and Computer Application in Analytical Chemistry

Informative but broad
An informative book that covers a wide range of topics in chemometrics. About a third of the book deals with statistics, giving a good review to signal processing, ANOVA, t-tests, etc. For someone that wanted a book dealing only with chemometrics, it is disappointing to find a big portion of the book dedicated to basic statistics. A lot of topics are covered but not all in much detail. For example, there are 3 pages on SIMCA, 4 pages on PCR and PLS. There are more details when you get into the sections on neural networks and fuzzy theory. The examples are OK but not always easy to follow if you are not familiar with a particular method because steps are skipped. This book is a great overview of chemometrics-useful to refresh memories or get new ideas for data treatment- but needs to be supplemented with additional resources to learn more any one particular method. Fortunately the author includes a "general reading" section at the end of each chapter which provides references for books with more details.

How to Use Excel in Analytical Chemistry and in General Scientific Data Analysis

How to use Excel in Analytical Chemistry by Robert de Levie
Excellent book setting out applications in Chemistry using Excel. Well chosen examples embracing spectroscopy, chromatography, electrochemistry, kinetics and acid-base theory illustrate the ease of minipulation of data via Excel. The section on Fourier Transform I really liked, and this is followed by a good coverage of noise filtering and deconvolution.

Didactic and academic
This is a book which wold like to be a text book and not a popular one. No CD or disk with the exampels is provide. Only the macros could be downloaded from the web. This book contain many exampels. Most of the exampels are in the sort of instructions i.e. 1. open a new spreadsheet 2. enter the label.. 3.In row 11, starting with cell A11 enter the labels pH, [H+]....

15.anchor the graph on cell b1,... etc.

The point is that there are much words in this book and less figures which show the Exell worksheet after each/everal instruction. That make this book to be less fraindly then other books on Ecell.

nice
I'd give it 5 stars, but I've only used about 3 pages thus far.

Statistics and Chemometrics for Analytical Chemistry

I don't know this edition, but the 2nd Edition is great!
I don't know this edition, but I think the 2nd edition is great! I'm a Ph.D. chemist, but wanted to learn more statistics, and learn it better. I found this book concise, and I thought the authors explained fundamental concepts and did so with admirable clarity. Me and many of my colleagues consider it our best reference on statistics!

Very useful book!
This is an excellent statistics book for chemists. It has good examples of data from chemical assays and provides relevant analysis of the data to illustrate the points. I work in the pharmaceutical industry and I use it all the time, to give myself a good, all-round understanding of statistics for chemistry. This book doesn't go into in-depth statistics, so if you need something more meaty, look elsewhere. Overall, I found this book to have everything I've needed. I recommend it highly.

Basic stats, just more complicated!
The book overall is a highbrow explanation of elementary statistics, applied to a chemist's world. It does not do a very good job of explaining your base statistics, so I would recommend only people that have had some true statistics courses and background use this book. It provides good examples from an analytical chemist's point of view, but beyond that, the book is useless.
