The CD-ROM has instructional multimedia showing step by step how the programs are used for the problems in the book. It contains the programs and extensive sample data files. The results can be validated as OSCAR calculates confidence intervals for the spectra and elution curves.For users who do not want to enter the programs by hand a separate CD-ROM is available. The main emphasis is a discussion of a deconvolution method, OSCAR (Optimization by Stepwise Constraining of Alternating Regression), developed by the authors. Principle component analysis is described and used as a useful tool. Basic signal processing is described by illustrative examples.The main part of the book describes the deconvolution of overlapping chromatographic peaks.
The reader can see how searches in spectral libraries can be greatly speeded up by proper formulation of the calculation. Practical working algorithms such as the Savitzky-Golay smoothing method are emphasized. The first part of the book describes how data iscollected, converted and prepared for the actual deconvolution. The mathematical principles needed for the proper treatment of experimental data are thoroughly described. All programs can be read, tested and modified by the user. Based on a concrete set of working MATLAB programs, the book begins with a short program of snippets describing basic principles and proceeds to a complete application program filling a central analytical need: obtaining pure spectra from the observed overlapping spectra, with standard deviations for thesolutions obtained.The strength of the book is the open nature of the programs.
