  • Patent number: 4827134
    Abstract: 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 all substances could be completely eliminated from the surface of the carrier. Now, the invention provides for a thermal decoupling of the carrier from the cooling device. Such decoupling allows to heat the carrier to higher tempreatures and to reduce the time needed for performing a measuring cycle, since as a result of the decoupling the cooling device is not heated but the heating is limited to the small mass of the carrier.
