This unique handbook explains the most commonly used terminology and places each term in context. Concepts are described in a way that make them meaningful to practitioners and in line with ¿official definitions¿ developed by international organizations.
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 solutions. pH meters and electrodes are then discussed, including selection criteria and the care of electrodes. Finally, sections on making pH measurements and uncertainty are followed by a set of practical exercises. Measurement of pH is one of the Practical Laboratory Skills Training Guides, a series that aims to make achieving best practice easy. These invaluable manuals will enable both experienced and inexperienced staff to get the essential basics of any experiment right simply by following the clear and easy to use instructions provided. The guides are written by experienced scientists and include minimal theory, plenty of practical exercises in order to assess competence, and trouble shooting information. Other titles are: Measurement of Mass; Measurement of Volume; High Performance Liquid Chromatography; and Gas Chromatography.
This document provides guidance on various important aspects of volume measurement as it is commonly carried out in analytical laboratories. Although the measurement of volume with such items of equipment as pipettes, graduated flasks, syringes, etc. is seemingly a routine procedure, the operation is by no means foolproof. The analyst should approach volume measurement with the same care and critical appraisal that is (or should be) applied to the more 'exciting' parts of an analytical investigation." - page 1.
Love, life, writing and friendship are the intimate subjects of letters between three intelligent, witty women who shared a passionate commitment to Australian literature. These carefully selected letters tell a story that reads like a novel. Their correspondence - from the late 1920s to the mid-1950s - reveals their public battles as well as their private ones. Their personal conflicts are a microcosm of Australian society's struggles over the period.
