Solid sorbents are being used extensively to sample contaminants in air. This technique has proven valuable, not only to the industrial hygienist because the solid sorbent sampling tubes are easy to use and transport, but also to the analytical chemist who finds the analytical procedures straightforward and adaptable to a wide range of compounds. Since the integrity of the sample depends on the nature of the compound and sorbent and on the effects of a number of other parameters, it is important, if not essential, to obtain laboratory validation data before using the technique for obtaining monitoring data. Field spiking and conformation studies are also recommended to determine the effects of the specific plant atmosphere and other sampling variables under actual field conditions. This paper gives guidelines for designing both laboratory and field validation studies.
