THE MAK-COLLECTION FOR OCCUPATIONAL HEALTH AND SAFETY. PART Ⅲ: AIR MONITORING METHODS

摘要

The tenth volume of the series ,,Analyses of Hazardous Substances in Air" is the second one published under the new title "The MAK-Collection for Occupational Health and Safety, Part Ⅲ, Air monitoring Methods". This volume extends the range of air monitoring methods by ten additional procedures. The first two chapters deal with the gas chromatography/mass spectrometry analysis and molecular spectroscopy in the ultraviolet and visible range. Mass spectrometry is largely recognized as a very powerful method for the analysis of mixtures of organic compounds. In this respect, chapter one discusses the chromatography/mass spectrometry analysis. The ionization methods, inlet and vacuum systems, analysers, and detection systems are presented. Examples as analysis of solvents by quadrupole mass spectrometry in full scan mode, and analysis of polychlorinated biphenyls by ion trap mass spectrometry are illustrated. The second chapter deals with molecular spectroscopy in the ultraviolet and visible range. The principle of molecular spectroscopy and the design of a spectrophotometer are presented. Samples handling and measurement and the main factors influencing the position and intensity of UV/VIS bands (effect of solvent, pH and temperature) are also discussed.
