Abstract

The invention discloses a system and method for online adjustment of the ionization environment of a mass spectrometer. The system is installed on the mass spectrometer or between the chromatographic column of the chromatographic instrument and the mass spectrometer, and at least includes a controller, a pump, a connecting pipeline, a connecting pipe fitting and a regulating liquid container ; One end of the connecting pipeline is connected with the chromatograph, the other end is connected with the mass spectrometer, the middle is connected with the pump through the connecting pipe, and the pump is connected with the regulating liquid container through the connecting pipeline. When optimizing the detection conditions, by controlling the switch and flow rate of the pump, input different types or different flow rates of conditioning fluids in the same mobile phase to obtain the ideal ion type and response intensity; Regulators with different flow rates can adjust the composition of the mobile phase online, change the ionization environment of the compound in the ion source in real time, meet the needs of simultaneous detection of compounds with different properties, save the amount of chemical reagents used, and improve the efficiency of analysis and testing.

Description

technical field [0001] The invention belongs to the technical field of detection and analysis of mass spectrometers, and in particular relates to a system and method for on-line adjustment of the ionization environment of a liquid chromatography mass spectrometer. Background technique [0002] Liquid chromatography-mass spectrometry is an instrument combined with liquid chromatography and mass spectrometry.
