As a means for connecting a gas chromatograph and an IR-spectrometer, devices are used which include a cooled carrier which allows to condensate the substances supplied by the gas chromatograph on its surface where they may be examined by spectroscopy. The examination of a new sample makes necessary the evaporation of the substances condensated on this surface before. Up to now, the heating and the cooling of the carrier which was necessary to this end, took a rather long time. Further, the heating of the carrier was limited to a temperature at which not...


Device for collecting samples to be analyzed by spectroscopic examination, comprising a carrier being movably arranged inside a housing, which is adapted for being evacuated, and provided with a drive and means for introducing its surface into the ray path of the spectrometer, and comprising further a cooling device provided with a cooling head projecting into the housing and being thermally coupled to the carrier, and a nozzle directed upon the surface of the carrier for supplying a sample in the gaseous state for analization thereof, characterized in t...
