| Abstract: | A liquid chromatography method using UV detector and ESI mass spectrometry has been developed by which the mean relative molecular mass of sodium alkylbenzenesulfonates can be determined without any pre treatment. The results conformed to those by desulphonation/GC method. Compared with the more complicated, time consuming GC method, the HPLC method is fast and simple. |
