From May 22 to 25, 2026, Assoc. Prof. Liu Zhongshan from the Institute of New Concept Sensors and Molecular Materials at Shaanxi Normal University attended the “Chinese Chemical Society Fourth National Conference on Mass Spectrometry Analysis” in Beijing. He presented an oral report titled “Miniaturized liquid chromatography detector for the sensing of perfluoroalkyl substances” at the Environmental Analysis Session, introducing the principles behind the development of miniaturized liquid chromatography detectors based on film fluorescence sensing technology and presenting research findings on the separation and detection of perfluorinated organic pollutants.

The conference was organized by the Mass Spectrometry Analysis Committee of the Chinese Chemical Society, the Mass Spectrometry Branch of the Chinese Physical Society, and the Chinese Society for Analytical Chemistry, and hosted by the State Key Laboratory of Environmental Chemistry and Ecotoxicology at the Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences.
