Description

technical field [0001] The invention relates to mass spectrometry, in particular to a chromatographic and mass spectrometry coupled system. Background technique [0002] Liquid chromatography and gas chromatography systems are commonly used analytical instruments. In liquid chromatography, the fluid can be an organic liquid solvent, an aqueous liquid solvent or a mixture of organic and aqueous solvents and the effluent is a liquid. In gas chromatography, the fluid is the carrier gas and the effluent is gaseous. [0003] The samples that can be directly separated by GC are volatile and thermally stable, and the boiling point generally does not exceed 500 °C. According to relevant statistics, 20% to 25% of the currently known compounds can be directly analyzed by GC, and the rest can be analyzed by LC in principle. [0004] Chromatographic analysis can be performed on gaseous or liquid samples. Once the samples are separated, they may require further analysis to determine ...
