Abstract

Environmental hazards are often detected by gas chromatography, mass spectroscopy, or high performance liquid chromatography. These methods are well characterized, but they are expensive and usually not performed on-line. Antibody-based technologies are increasingly being applied due to the specificity of the antibodies, and the low cost of the detection kits. With the immunoassay kits, personnel collect samples, mix them with the kit components, and observe the results on-site.
