||Chromosorb 101 efficiently trapped vapors of hexachlorobenzene (HCB) and hexachloro-1,3-butadiene (HCBD) from air at a sampling rate of 3 l./min. No loss of efficiency was noted with sampling times of up to 3 hr. Increasing the sampling rate to 10 l./min. for 1 hr decreased the efficiency by 20%. The method as described has a detection limit of 28 ng of hexachlorobenzene per cubic meter of air.
