What instruments does Lcms use?

Femtosecond detection center uses liquid chromatography-mass spectrometry (LCMS), which generally consists of injection system, ion source, analyzer and detector. It also includes auxiliary equipment such as vacuum system, electrical system and data processing system. Liquid chromatography-mass spectrometry (LC-MS) mainly solves the following problems: the analysis and determination of non-volatile compounds; Analysis and determination of polar compounds; Analysis and determination of thermally unstable compounds; Analysis and determination of high molecular weight compounds (including protein, peptides, polymers, etc.). ); There is no commercial spectrum library to compare and query, so we can only build our own library or analyze the spectrum ourselves.
