Method of evaporating sample solutions in tubular atomisation devices

摘要

The invention relates to a method of evaporating sample solutions in tubular sample reception devices for atomic absorption and atomic emission spectrometry and can be used for all trace analysis by atomic spectroscopy. It is characterised in that the evaporation is carried out by lowering the pressure to a range of 10-50 torr and, during evaporation, a gas flow is maintained in the direction of the longitudinal axis of the pipe from both pipe ends to a feed orifice (dosing orifice) provided in the middle, with the gas being pumped out via this feed orifice.
