ABSTRACT:
A sample injection device for gas chromatography with a heated evaporation chamber and an adjoining split chamber for splitting the flow, in which carrier gas is introduced into the evaporation chamber and into the split chamber through respective valves. Up until the evaporation of the sample, carrier gas is conducted only into the split chamber and after evaporation, only into the evaporation chamber giving a chromatography process using capillary columns which operates with very small amounts of sample.
