The research group mainly focus on the design and development of flow injection chemiluminescence, static chemiluminescence, capillary electrophoresis, microfluidic chips and mass spectrometry interface instruments. We have obtained a number of national invention patents associated with the instruments. In the sample pretreatment device, we developed online preconcentrate trace metal composition of natural gas and the estrogen in environmental water samples, magnetic microparticles, molecular imprint, membrane extraction, cell capture materials or critical components.
