ABSTRACT:
The device allows microsamples to be introduced into the ionization source of the spectrometer. It includes a reactor with means for introducing the microsample, means for heating the microsample, means for connection with a vacuum source and means for feeding an adjustable flow of reagent for transforming the microsample into gaseous compounds; a restricted and calibrated passage for flow of the gases from the reactor; and a sublimation tube connected on the one hand to the passage and, on the other, to the ion source of the spectrometer through a valve having means for bringing it to an adjustable cryogenic temperature.
