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.
描述了一种用于气相色谱 - 质谱法对空气进行超痕量分析的采样和进样新方法。在这项新技术中,进样过程中在气相色谱柱上会发生预分离,因为在进样期间共冷凝的大气成分,我们将此方法称为“压力进样”(Druckaufgabe)。该方法不仅具有理论价值,还在职业和环境问题方面具有潜在的广泛应用。
