Guide to pH measurement
Guide to pH measurement
The theory and practice of laboratory pH applications.

This guide focuses on giving a clear and practical description of how to measure pH in the laboratory environment. A lot of tips and hints are given for the important points and the whole measurement description is later backed up by the theoretical description of acidity and alkalinity measurements. Attention is also given to the different kinds of pH electrodes available and the selection criteria for choosing the right electrode for a specific sample.

Guide to conductivity and dissolved oxygen
A Guide to conductivity and dissolved oxygen
The theory and practice of conductivity and dissolved oxygen measurement.

This guide to conductivity and dissolved oxygen measurement is one of a series produced over the past few years, covering analytical techniques such as pH and ion selective electrode Analysis. As well as an insight into the theoretical aspects of the techniques, sections covering applications and troubleshooting have been included to make this a comprehensive review of the measurement of these important parameters.

 
Guide to ion selective measurement
Guide to ion selective measurement
The measurement of the concentration or activity of an ion in a solution by means of an Ion Selective Electrode is as simple as making a routine pH measurement. A pH electrode is only a rather special case of an almost perfectly selective Ion Selective Electrode but the principles and practice are the same in both cases. The chief difference between the pH electrode and other electrodes is that the latter, generally speaking, are not as selective as the pH electrode and some account must be taken of possible interferences in an analytical situation.

The information contained in this booklet should enable the reader to understand the principles of operation and methods of analysis involving Ion Selective Electrodes.
