Abstract:
This invention collects and analyzes condensable gases using a cryogenic cooling device connected to a charcoal cold trap assembly. More particularly, it uses a removable cryogenic cooling device instead of liquid nitrogen to trap condensable gases. The invention has four major components: (1) a removable cryogenic cooling device (2) a vacuum canister, (3) a cold trap canister filled with activated charcoal, and (4) a cover assembly with welded inlet/outlet tubes and an o-ring seal between the cover assembly and the vacuum canister.
