Development of Air Sampling and Analytical Methods for Toxic Chlorinated Organic Compounds.
NIOSH 1979 Dec:54
An air sampling and analytical method for the determination of hexachlorobutadiene (87683) (HCBD) in air was developed. HCBD was collected from air with a solid sorbent and desorbed with hexane. A known volume of air was drawn through an Amberlite XAD-2 tube to trap HCBD vapor. The analyte was desorbed from the sorbent with hexane and an aliquot of the resulting solution was analyzed using a gas chromatograph equipped for electron capture detection. The front and rear sections of the sorbent tube were analyzed separately; the rear section was used as a breakthrough indicator. The method was partially tested using sample loadings of 4 to 3,000 nanograms per sorbent tube for the supporting analytical method. The complete method was tested with air containing approximately 10 to 2000 micrograms per cubic meter of HCBD at temperatures of 25 to 28 degrees C at a relative humidity of over 90 percent. The method was tested and modified until valid results were obtained.
