FREE moisture analysis monograph
Water determination is one of the most frequently performed analyses in laboratories around the world: this FREE monograph first describes the basics of the Karl Fischer titration technique
Water determination is, together with the measurement of the pH value and acid-base titrations, one of the most frequently performed analyses in laboratories around the world This is not really surprising, as the water content directly influences the quality, processability, shelf life and stability of a wide range of products

Online ion chromatography from Metrohm has enabled tighter process control of acid pickling baths, as the final cleaning stage prior to metal plating
Various physical and chemical methods are used to determine the water content.
Among these, the Karl Fischer titration has established itself as a reference method for general use.
It is characterised by its high specificity and precision, and works over a wide concentration range from ppm up to 100%.
An additional advantage are the short determination times.
This FREE 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 working instructions 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. Request a free brochure from Metrohm UK ...
