Evaporator tube for the evaporation of liquid samples for the capillary gas chromatography -

摘要

Evaporator tube for the evaporation of liquid samples for the capillary - of gas chromatography, which is provided with at least one constriction, characterized in that(a) the evaporator tube (22) on its entire length for the flow of the sample and of a carrier gas stream is open and(b) the constriction (24a to 24e) is designed in such a way that in the region of the constriction (24a to 24e) a strong increase in the flow velocity of the carrier gas stream and thus a negative pressure develops.
