METHOD OF MEASURING VOLATILE ORGANIC COMPOUND IN ENVIRONMENTAL ATMOSPHERE

摘要

PROBLEM TO BE SOLVED: To provide a method of measuring the concentration of a volatile organic compound including volatile chlorinated hydrocarbon in the environmental atmosphere.SOLUTION: The method of measuring a volatile organic compound in an environmental atmosphere is provided in which: the environmental atmosphere is contacted with a dehumidification agent; the environmental atmosphere is caused to flow in a collection tube filled with absorbent for the volatile organic compound, at a constant flow for the predetermined time; at this time, total amount of gas discharged from the collection tube is collected into a resin bag having an aluminum layer; and then the volatile organic compound desorbed from the absorbent for the volatile organic compound and the volatile chlorinated hydrocarbon in the gas collected in the resin bag are quantified. The total amount of the quantified volatile organic compound and volatile chlorinated hydrocarbon is a measurement value of the concentration of the volatile organic compound including the volatile chlorinated hydrocarbon.
