pH Measurements is a seven-chapter simplified text on obtaining a high degree of accuracy in practical pH measurement. The introductory chapter of this book relates the principles of pH measurements to the actual measurement. This chapter specifically tackles the factors involved in the measurement and what magnitude of effect does each factor have on the measurement. These topics are followed by discussions on the components of pH equipment and technique, including the electrodes and buffers. A chapter considers the general approach of pH measurements and illustrates with examples of some common difficult samples. The concluding chapter shows the isolation and correction a pH equipment malfunction. pH equipment operators and users will find this book rewarding.

Metrological traceability of chemical measurement results means the establishment of a relation to metrological stated references through an unbroken chain of comparisons. This volume collects 56 outstanding papers on the topic, mostly published in the period 2000-2003 in the journal "Accreditation and Quality Assurance". They provide the latest understanding, and possibly the rationalenbsp;why it is important to integrate the concept of metrological traceability including suitable measurement standards such as certified reference materials, into the standard measurement procedures of every analytical laboratory. In addition, this anthology considers the benefits to both the analytical laboratory and the user of the measurement results.

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.

It is now becoming recognized in the measurement community that it is as important to communicate the uncertainty related to a specific measurement as it is to report the measurement itself. Without knowing the uncertainty, it is impossible for the users of the result to know what confidence can be placed in it; it is also impossible to assess the comparability of different measurements of the same parameter. This volume collects 20 outstanding papers on the topic, mostly published from 1999-2002 in the journal "Accreditation and Quality Assurance." They provide the rationale for why it is important to evaluate and report the uncertainty of a result in a consistent manner. They also describe the concept of uncertainty, the methodology for evaluating uncertainty, and the advantages of using suitable reference materials. Finally, the benefits to both the analytical laboratory and the user of the results are considered.
