Copyright © 2010 John Wiley & Sons, Inc. Figure Air Sampling Tubes with Activated Charcoal, Charcoal tubes have two sections, the primary section and the backup section. The primary section is extracted to determine the amount of the air contaminant from the charcoal. Air is actively drawn through the tube during sampling and the air volume is measured so that the amount of contaminant divided by the air volume gives air concentration. The backup section is used to detect if the primary section was overloaded. (Courtesy of SKC, Inc., Eighty Four, PA)

Copyright © 2010 John Wiley & Sons, Inc. Figure Passive Sampling Badge, The passive sampling badge contains a sorbent or a filter coated with a specific reactant that traps the contaminant(s) in the air. Passive monitors work by diffusion of the contaminant from the surrounding environment into the sorbent and the determination of the average air concentration is determined by validation testing.
