CARRIER GAS CONNECTION DEVICE FOR GAS CHROMATOGRAPHS

Abstract:

Carrier gas connection devices (100, 402, 404, 406, 408) enable one to change the carrier gas provided to a gas chromatography channel. The carrier gas connection devices (100, 402, 404, 406, 408) comprise a channel adaptor (102, 202), a carrier block (104, 302), and a clamping system, and two or more channel adaptor positions. In each of the channel adaptor positions, a fluid-tight flow path for carrier gas out of the carrier block (104,302) into the channel adaptor (102, 202) is formed. Carrier gas distribution systems (400), gas chromatography instruments, and methods of changing a carrier gas supplied to a GC are also provided.
