Название: Derivative spectrophotometry. Low and higher order

Автор: Talsky G.

Аннотация:

Derivative spectrophotometry is a versatile tool for the quantitative estimation and analysis of substances. This book provides the theoretical background and the practical instructions necessary for using this highly efficient analytical technique.

Drawing on carefully selected examples, the author points out the advantages and drawbacks of the various methods and reveals common pitfalls.

Features include:
* theoretical background
* instrumentation
* practical aspects
* applications

Spectroscopists and analytical chemists in industry and academia will value this book as an indispensable guide to the use of derivative techniques in spectroscopy.
