ABSTRACT:
An in-torch vaporization sample introduction system for introducing a sample to be analyzed into a spectrometer, comprising a sample holder means for carrying the sample to be analyzed, a modified Fassel-type torch having a plasma fed by inert gas through outer and intermediate feed channels in an enlarged gas tube, an inner axial tube having one end open adjacent the plasma and an opposite end open for receiving the sample holder for feeding the sample to the plasma, the inner axial tube tapering to a reduced diameter adjacent the one end to form a well defined channel for feeding the sample to the plasma. The sample holder is positioned in the inner axial tube a predetermined distance below the plasma, and the opposite end of the inner axial tube is sealed for vaporizing the sample.
