Claims

[Scope of utility model registration request]

In a column connection adapter that connects the column outlet of a gas chromatograph or the like and the inlet of a detector such as a thermal conductivity type detector, when connecting a SUS force ram instead of a glass force ram, a hollow metal fitting on the detector inlet side is used. At the other end, a threaded part was provided to connect the SUS force ram, and the other end was made into a bar with the same outer diameter as the glass force ram, and this was inserted and screwed, and this part was used as the SUS force ram adapter. When,
A column connection adapter characterized by having a structure in which the gas flow path does not pass through to the tip after passing from the SUS force ram connection part to the middle of the SUS force ram adapter, but comes out from the shaft center to the side in the middle.
