• Inline techniques for IC sample preparation (Dr. H. Schäfer)
• Dialysis as an automatable sample preparation technique for ion chromatography (Dr. W. Frenzel)

This monograph first describes the basics of Karl Fischer titration. It covers not only the KF reagents, chemical reactions, volumetric and coulometric titration as well as the different detection methods, but also deals with aspects such as interfering side reactions and sample preparation techniques.

The second part of the monograph contains detailed procedures for the determination of water in different samples and covers more than 900 substances. The spectrum ranges from raw materials through cosmetics, pharmaceuticals, foodstuffs and plastics up to gaseous samples.

The monograph offers an easy-to-read introduction into the basics of polarographic and voltammetric trace analysis.

Numerous textbooks about electrochemistry already exist and are an indispensable basis for every scientist. Prof. Dr. G. Henze does not want to add another one to the extensive list. Instead, the basics are reduced to those topics that are relevant for polarographic and voltammetric trace analysis.

On just 60 pages the most important current measurement techniques are described in an illustrative matter with self-explanatory figures: Direct current methods, pulse methods as well as alternating current methods are covered. Polarographic methods and the various types of stripping voltammetric techniques are the second main focus. Chapters about instrumentation and sample preparation complete the monograph.

The monograph is recommended for everyone who wants to know more about trace analysis using polarography and stripping voltammetry.

The Metrohm Monograph «Practical Voltammetry with the VA Computrace» complements this booklet in an ideal way. Practical hints supplement the background information and basics.

A literature reference book for different types of air analysis

Authors: Dr. Markus Läubli, Deepak Parab, Dr. Kai Henning Viehweger

Analytical techniques such as chromatography that are based on separations are – without a further technique used for detection – not capable of use as complete, quantifying analytical methods. The choice of the detection principle is determined by the requirements of the selected separation principle and the properties of the analytes or the matrix. In ion chromatography the answer to the detector question is usually «conductivity detection».

Detection techniques that differ from conductivity detection will be briefly described under the term «advanced detection techniques» and compared with one another. The spectrum ranges from UV/VIS detection through electrochemical detection principles right up to modern atomic spectrometry and
mass spectrometry detectors.
