GAS CHROMATOGRAPH AND GAS CHROMATOGRAPHIC MASS SPECTROMETER

PURPOSE:To obtain a GC/MS (gas chromatographic mass spectrometer) in which only a desorbed component can be analyzed by condensing a laser light or an infrared light locally thereby desorbing a contaminant from the local part. CONSTITUTION:Particles are desorbed tram the surface of a sample 4 by mea...

description	PURPOSE:To obtain a GC/MS (gas chromatographic mass spectrometer) in which only a desorbed component can be analyzed by condensing a laser light or an infrared light locally thereby desorbing a contaminant from the local part. CONSTITUTION:Particles are desorbed tram the surface of a sample 4 by means of a condensed laser light 6 and separated into components through chromatograph before being subjected to mass spectrometric analysis. In such GC/MS 1, the window of a sample chamber 3 is employed as a clean surface member for adsorbing the desorbed particles. After the particles are adsorbed to the surface of window, the sample 4 is taken out of the sample chamber 3 which is then heated entirely in order to liberate the adsorbed particles and to feed the liberated particles to a GC part.
