Abstract
The cryogenic trapping system traps organic arsenicals within a centrally-positioned cryotrap body and allows inorganic arsenical to flow through the cryotrap body. As a hydride gas is directed into the central cryotrap body, the gas is cooled by a pair of Peltier units that sandwich the cryotrap body so that the cold side of each of the Peltier units abuts the cryotrap body. The hot side of each Peltier unit abuts a heat exchanger—which cools the Peltier unit. In the preferred embodiment, organic arsenicals are trapped in a sorbent bed within the cryotrap body.
