The volatility of these compounds facilitates the use of gas chromatography (GC) for separation and quantitation. There are many factors to consider when choosing or implementing a chromatographic method for the analysis of one or more VOCs, including the intended use [medical diagnosis, forensic applications, general screen, quantitation of specific

Method 25 applies to the measurement of volatile organic compounds (VOC) as nonmethane organics (TGNMO), reported as carbon. Organic particulate matter will interfere with the analysis, and, therefore, in some cases, an in-stack particulate filter will be required. The method requires an emission sample to be withdrawn at a con-... 

Nowadays, additional functions become important and the performance should be tested. For instance, since the use of Pb solder is nowadays prohibited by the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS), conductive adhesives are used instead. For the adhesives, electric conductivity and shear resistance are vital, and their tests, besides other conventional tests, should be conducted. Thus, some adhesives developed in the future may have novel functions that conventional adhesives do not have, and new test methods and standards should be required to check the functions. From the environmental point of view, measurements of volatile organic compound (VOC) emergence and dismantlability of adhesives will become more important in the future (see O Chap. 58).
