Chromatographic Techniques in Industrial Hygiene

Abstract

Chromatographic techniques in industrial hygiene are defined as those separation and analysis techniques that rely on the separation of multiple chemical constituents by taking advantage of the differential adsorption, absorption, mobility, or affinity of the components in a system with a stationary phase (solid, liquid coated on solid, reactive substituent attached to solid surface, ion‐exchange resin, etc.) and a mobile phase (gas or liquid) that transports the separated constituents to a detector for immediate identification and possible quantitation or to a collector for later identification and possible quantitation.By industrial (occupational) hygiene is meant that science and art, which is the anticipation, identification, assessment, and control of chemical and physical hazards in the workplace (meant to include offices, places of business, retail establishments, and schools) and home. Included among those methods that make possible the identification and assessment of such hazards are those methods that are used to determine the concentration of airborne and surface chemical contaminants, as well as those that assess levels of exposure to chemical contaminants by the analysis of exhaled breath, blood, urine, or other biological samples.
