The invention relates to an ion source which comprises a leading-out pole plate, a first insulating part, a first grounding plate, a first sleeve, an ion focusing module, a second grounding plate, a connecting piece, a reflector and a deflection module, wherein the leading-out polar plate is connected with the first grounding plate through the first insulating part, one end of the first sleeve isconnected with the first grounding plate, and the other end of the first sleeve is connected with the ion focusing module, an interval is formed between the second grounding plate and the ion focusingmodule, and the second grounding plate is connected with the ion focusing module through a connecting piece, the reflector is arranged on the second grounding plate, and the deflection module is arranged on the second grounding plate. Since the leading-out pole plate, the first insulating part, the first grounding plate, the first sleeve, the ion focusing module, the reflector and the deflectionmodule are assembled into a whole, which is different from a traditional design of an ion source with independent components, assembling and replacing operations can be conveniently carried out on a mass spectrometer.
Description
technical field [0001] The invention relates to the technical field of detection instruments, in particular to an ion source and a mass spectrometer. Background technique [0002] A mass spectrometer mainly includes an ion source, a mass analyzer, and a detector. Among them, the ion source is used to accelerate, focus and deflect the initially dispersed ions into the field-free flight area by using the electric field generated by the combination of the pole piece and the electric system. The mass analyzer separates ions of different masses and sends them to the detector in sequence for detection. The dual-field acceleration area, ion focusing system, ion deflection system, and optical introduction system of the traditional ion source are independent of each other, making assembly and replacement difficult. Contents of the invention [0003] Based on this, it is necessary to overcome the defects of the prior art and provide an ion source and a mass spectrometer, which can...
