This guide explains the best methods for undertaking the measurement of volume, one of the most frequent operations in the laboratory. It is required when obtaining a known quantity of a sample for analysis; for preparation of analytical reagents; and for preparation of calibration standards and quantitative analysis by titrimetry. After an initial section covering the units of volume and other terminology, the various types of volume measuring apparatus are then described. Later sections cover the importance of temperature, calibration, accuracy and use of the different types of apparatus,...

Whether pH is being used to test a sample against a legal requirement or specification; as part of an analytical method; for monitoring and controlling a reaction; as a process control in the chemical industry; or for the environmental monitoring of waste and effluents, it is important that all pH measurements are carried out in a logical and consistent manner, paying careful attention to experimental procedures, in order to obtain reliable results. This guide provides scientists with the knowledge of how to do just that, first by outlining the principles of pH measurement and buffer...

Gas chromatography has been the most widely used technique in analytical chemistry for over three decades. It offers unchallenged resolving power for closely related volatile compounds and high sensitivity and selectivity with many of the detector systems. This technique is very accurate and precise when used in the laboratory.
