Progress in the application of liquid chromatography and liquid chromatography-mass spectrometry technology in surfactant analysis
The applications of liquid chromatography(LC)and liquid chromatography-mass spectrometry(LC-MS)techniques in the analysis of surfactants were reviewed.The principles,advantages and disadvantages of various chromatographic modes and detectors for surfactants analysis were discussed,as well as the advancements of LC-MS technology in the structural identification,commercial product analysis,quality control,environmental monitoring,residue detection and metabolomics research of surfactants.And some limitations and challenges of LC-MS technology were summarised.Finally,the development trends of LC and LC-MS technologies were anticipated,and it is expected that the further popularization of high-resolution mass spectrometry(HRMS)technology,and two-dimensional liquid chromatography(2D-LC)technology,as well as the development of new chromatographic fillers and stationary phases,will significantly promote the development of surfactant analysis technology.
