A chromatographic analytical procedure has been developed for the gaseous impurities in concentrated acetylene gas manufactured from natural gas.In this work a thermal conductivity detector,a potentiometer recorder,and hydrogen as carrier gas were used. Column I packed with a mixture of salicylaldehyde and liquid paraffin as stationary liquid was used to separate and analyse the components such as allene,methylacetylene, butadiene,vinylacetylene,and diacetylene.The time required for a complete analysis is about 18 minutes. Column Ⅱ containing a serial packing of adsorbents of active carbon and Type 5A molecular sieve was used to analyse oxygen,nitrogen,methane,and carbon monoxide. Carbon dioxide,ethylene,and acetylene were analysed on column Ⅲ filled with active carbon and silica gel in series.Samples were injected separatively.The total time of analysis is about 20 minutes. The results of determination and computation indicate that the minimum detectable quantity of gaseous impurities is 1.16—36 ppm.With impurities ranging from 0.005 to 0.5%,the reproducibility expressed as relative average deviation is less than ±10%,and the accuracy expressed as relative average error is less than ±5%.
