Chemical Instrumentation: A Systematic ApproachWiley, 22 feb 1989 - 1210 pagine The Third Edition of this established work on chemical instrumentation has been completely rewritten and updated to account for the advances made since the Second Edition came out in 1973. More main methods of measurement are presented, and there is extended coverage of chromatography and electrochemistry. Most of the material is new--including coverage of microprocessors and microcomputers, statistical control of measurement quality, quantification and extraction of information, x-ray fluorescence spectrometry, surface spectrometric techniques, and chromatography and HPLC. The quality and range of the worked examples have been improved, and there are end-of-chapter exercises. |
