| Abstract: | The analysis of nonionic surfactants was investigated by reversed-phase liquid chromatography with mass spectrometry detection. On a C18 column, separation was achieved on the basis of chain lengths of both alkyl and ethoxy groups in a CH3CN/CH3OH/H2O/HAc solvent system. Peaks were identified by electrospray mass spectrometry. |
