Abstract

An embodiment of the invention provides a mass spectrometer. The mass spectrometer comprises an ion source, a capillary, a sampling cone, a hexapole, a first ion guide electrode, a second ion guide electrode, a first ion repulsion electrode, a second ion repulsion electrode, a flight tube, a detector and a dynamic lens board. The dynamic lens board controls the outlet voltage of the capillary and voltages of the sampling cone, the first ion guide electrode, the second ion guide electrode, the first ion repulsion electrode and the second ion repulsion electrode according to control signals of an upper computer. By means of the mass spectrometer, the upper computer can control the output voltage of the dynamic lens board at any time, so that the appropriate capillary outlet voltage and the voltages of the sampling cone, the first ion guide electrode, the second ion guide electrode, the first ion repulsion electrode and the second ion repulsion electrode are improved, and in-source collision induced dissociation is achieved. Further, the highest ion transmission efficiency is achieved, and the sensitivity and the resolution ratio are improved effectively.

Description

technical field [0001] The invention relates to the technical field of precision instrument manufacturing, in particular to a mass spectrometer and a dynamic lens plate. Background technique [0002] Mass spectrometer is an analytical instrument with high sensitivity, high resolution and high specificity for detecting the chemical composition of samples. The working principle of the mass spectrometer is: first convert the sample into gaseous ions, then separate the ions according to the mass-to-charge ratio (m / z) by an electric field or a magnetic field, then measure the intensity of the corresponding ions, and finally form a mass spectrum. According to the mass spectrum, the chemical composition of the sample can be obtained qualitatively or quantitatively. With the development of mass spectrometry, its application fields are becoming wider and wider. [0003] The mass spectrometer can only detect charged ions, so the ion source must be used to ionize the sample into ions...
