摘要
报道了一种氟里昂混合气体高效快速的气相色谱分析方法。采用6m×3mm填充柱,粒径为150~180μm的Porasil为固定相,H2为载气,热导池检测器,在柱温70qC时,将空气、F-12、F-125、F-143a、F-22和F-134a的混合物分离;可以对10^-6数量级的氟里昂进行定量分析。
A method for analysing freons gas by gas chromatography is reported. Air, Freon - 12, Freon - 125, Freon - 143a, Freon - 22 and Freon - 134a are effectively separated when the oven temperature is 70℃, using a 6 m ×3 mm column packed with porasil of 150- 180μm and a thermal conductivity detector. Trace amount of Freons gas at ppm lavel can be quantitatively analyzed by this method.
