Techniques which were available to the industrial hygienist for evaluating exposures to gases and vapors in the work environment were described. The applications and limitations of several sampling media and techniques were presented. General sampling considerations discussed included sampling strategies, and operational limits of sampling and analysis. Sampling media for gases and vapors included solid sorbents, activated charcoal, silica gel, porous polymers, tenax, proapaks, chromosorbs, XAD resins, other solid sorbents, multistage air sampling tubes, liquid absorbers, passive samplers, and flexible plastic bags/partially evacuated rigid containers. Desorption of contaminants and collection efficiency of solid sorbents were also discussed. Analytical techniques considered include gas chromatography, flame ionization detector, nitrogen/phosphorus detector, flame photometric detector, electron capture detector, hall conductivity detector, thermal conductivity detector, photoionization detector, high performance liquid chromatography, gas chromatography/mass spectrometry, volumetric methods, and ion chromatography. Quality assurance was discussed.
