Abstract
Sorbents for the collection and analysis of trace levels of the blister agent bis(2-chloroethyl)sulfide (505602) (mustard) in air were evaluated. Twenty three sorbents were screened and compared to Tenax, the polymer currently used by the Army. A gas chromatograph equipped with a flame photometric detector in the sulfur mode was used throughout the study and was configured for either sorbent evaluation or for recovery measurements. The screening technique used to select the sorbents whose predicted retention volumes at ambient temperature were greater than or equal to that of Tenax was based on the assumption that the sorbents would behave like chromatographic columns. While two promising alternatives to Tenax were demonstrated from the screening experiments, further testing revealed other problems which made them unsuitable for the collection and recovery of mustard. The author concludes that since the relationship between the log of the retention volume and the inverse of the temperature does not accurately predict sorbent capacity for small beds, the described screening technique is useful for purposes of comparison only.
