Fast and effective analysis of freon gas by gas chromatography

Zhongyi Yuan, Sanyo Electric

Abstract

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 150～180 μm and a thermal conductivity detector.Trace amount of Freons gas at ppm lavel can be quantitatively analyzed by this method.
