Gas trap apparatus |
摘要 |
A gas trap apparatus is disclosed for trapping gaseous fraction of mixtures. The apparatus includes a gas column chamber into which a tubular column, such as a capillary tube, may extend. A cooling chamber is provided into which a coolant may be introduced for solidifying or liquefying a gas sample. A heating element in surrounding relationship to the cooling chamber is used for vaporizing the solidified/liquified gas. A Dewar flask surrounds the gas trap apparatus to prevent thermal leakage to the atmosphere.
