[A new method for sampling and sample application in the ultra-trace of air by gas chromatography-mass spectrometry (author's transl)].
A new method is described for sampling and sample application in the ultra-trace analysis of air by gas chromatography-mass spectrometry. In this new technique, a preseparation occurs on the gas chromatographic column during sample application, since the atmospheric constituents that are co-condensed during sample application we call this method "Druckaufgabe" (pressure application). The method is not only of theoretical value. It has a potentially wide application to occupational and environmental problems.
