Qualitative Simultaneous Identification of Permanent and Hydrocarbon Gases by GC-TCD using Column Coupling Method

Abstract

The potential application of the GC-TCD using column coupling method was investigated by means of comparison with the single column method for the identification of gas mixture containing 5 inorganic and 6 hydrocarbon gases. The results indicate the useful of column coupling method, relative to the single column method. In addition, the flow rate of carrier gas and column temperature on the retention time of the target components have a notice-able effect. Application of the column coupling method for qualitative identification of the targeted components in natural gas samples indicate that the method can be used for routine work.
