Abstract

The invention relates to a flat linear ion trap. The flat linear ion trap comprises two PCB boards which are arranged oppositely; the surface of each PCB board is provided with a radio-frequency electrode, a first end cover electrode, a second end cover electrode, a front gate electrode and a rear gate electrode, which are positioned in the same plane, wherein, the radio-frequency electrode corresponds to the other PCB board; the first end cover electrode and the second end cover electrode are positioned at two sides of the radio-frequency electrode; and the front gate electrode and the rear gate electrode are synchronously positioned at two ends of the radio-frequency electrode, the first end cover electrode and the second end cover electrode; and an insulating clearance is arranged between the radio-frequency electrode and the first end cover electrode or the second end cover electrode. The more simplified flat linear ion trap provided by the invention, on the one hand, has higher storage capacity and ion trapping efficiency, and on the other hand, has the advantages of simple structure, easy process, low cost and the like, and is quite suitable for manufacturing a portable mass spectrograph with low cost.

Description

technical field [0001] The invention relates to an ion trap mass analyzer for a mass spectrometer, in particular to a flat linear ion trap. Background technique [0002] Mass spectrometry is one of the main analysis methods in the field of life science at present, and mass spectrometer is the most important analytical instrument. The core component of mass spectrometer is the mass analyzer. The biggest problem is to design a mass analyzer with simple structure, small size and low price. Among many mass analyzers, the ion trap mass analyzer has the characteristics of simple structure and low requirement for vacuum degree, so it becomes the first choice for manufacturing small mass spectrometers. [0003] Traditional ion trap mass analyzers are generally divided into three-dimensional ion traps and linear ion traps. The early three-dimensional ion traps were developed and patented by German scientist Wolfgang Paul and American scientist Hans Georg Dehmelt in the 1950s. At th...
