ABSTRACT:
A sample injecting device for a gas analyzer for injecting solvent-free, non-gaseous samples automatically or manually into the gas analyzer carrier gas, which device essentially comprises a vessel tightly connected to a furnace producing the vaporization or reaction temperature, which vessel is filled with said carrier gas and wherein a higher pressure prevails than in the furnace, a cassette located in the vessel, and exchangeable sample tubes located in the cassette, and means for moving the sample tubes automatically or manually, one at a time and at an adjustable velocity, into said furnace, wherein said carrier gas flushes the sample out from the sample tube, which means thereafter withdraws the sample tube into the cassette.
