Cold trap

摘要

A cold trap for collecting components of an aerosol stream comprises an elongated vessel provided with an aerosol stream inlet and an aerosol stream outlet, a cooling jacket for subjecting a substantial portion of the walls of the vessel to temperatures below 0 DEG C. and a baffle assembly that includes a plurality of spaced baffle plates which cooperate to present a tortuous path to the flow of the aerosol stream as it moves through the vessel.
