A gas Chromatographic (GC) technique is presented for the analysis of acid gases, alkanolamines and their degradation products in solution. The GC technique uses a Tenax GC column with a thermal conductivity detector. This simple and reliable GC technique can determine acid gases, alkanolamines and water in the solvent by a single sample injection and requires less time as compared to other existing analytical methods. The acid gases used in this study are CO2 and H2S and the alkanolamines used are monoethanolamine, methyldiethanolamine, 2-amino-2-methyl-1-propanol, diethanolamine and their degradation samples. This method has been compared to conventional techniques and the advantages of the GC technique have been demonstrated.
