Gas chromatography(GC). The use of GCs for detecting organics is rapidly becoming a standard technique in air pollution analysis.... GC systems are reliable, expensive and extremely sensitive.... Commercial GC systems are provided by many companies, and systems by Finnegan, Hewlett-Packard and Varian are among the better known. Commercial ambient monitoring GCs are made by Bendix(8200) and Beckman(6800) and are called Ambient Hydrocarbon Monitors. Total organic content of the air with and without methane is measured with GC-FID systems.  1, record 6, English, - ambient%20hydrocarbon%20monitor

Filter Sampling. Particulates are extremely varied for their composition. The monitoring of particulates with High Volume(Hi-Vol) samplers and other filter media varies from a simple colorimetric measure of the coefficient of haze(CoH) to the use of neutron activation analysis, atomic absorption spectroscopy, etc. for metal concentrations and gas chromatography for organic composition. Heavy metal measurements for lead, cadmium, chromium, vanadium, and nickel are common in urban areas such as with the National Air Pollution Surveillance Network(NAPS).  1, record 7, English, - filter%20sampling
