ABSTRACT:
A sleeve unit for converting a liquid sample into a sample gas and for mixing the sample gas and a carrier gas into a uniform gas mixture and delivering the gas mixture to the inlet end of a capillary tube of a gas chromatograph comprises a tubular liner having a bore, an inlet expansion chamber in the bore for changing a liquid sample into a sample gas, a mixing chamber in the bore next to the inlet chamber, a spiral core baffle inside the mixing chamber for thoroughly mixing the sample gas and the carrier gas into a uniform gas mixture by guiding the sample gas and the carrier gas into a spiral path around the spiral core baffle between the baffle and the liner, and an outlet chamber next to the mixing chamber for delivering the thoroughly mixed sample and carrier gases to an inlet end of a capillary tube of a gas chromatograph.
