Problems solved by technology

[0005] At present, there is no domestically produced quadrupole mass spectrometer in our country, which not only seriously restricts the development of natural science research in our country, but also makes our scientific research subject to foreign countries, making it difficult to produce original scientific research results

Abstract

The invention discloses a quadrupole mass-spectrometer which comprises an ion generation mechanism, a quadrupole rod filtering mechanism, an ion detection mechanism and a supporting connection mechanism. Gaseous ions are generated in the ion generation mechanism, guided out, accelerated, focused and then emitted into a quadrupole rod. Direct voltage and alternating voltage are overlapped on the quadrupole rod, so that ions with corresponding mass-to-charge ratios penetrate and are detected by a Faraday cup; accordingly, the components and residual amount of gas are obtained; compared with other mass-spectrometers, the structure and circuit of the quadrupole mass-spectrometer is simpler and lower in cost.

Description

technical field [0001] The invention relates to the field of vacuum equipment, in particular to a quadrupole mass spectrometer. Background technique [0002] Mass spectrometry is currently widely used in various disciplines to identify compounds by preparing, separating, and detecting gas phase ions. Mass spectrometry can provide a wealth of structural information in a single analysis, and combining separation techniques with mass spectrometry is a breakthrough in separation science methods. Among many analytical testing methods, mass spectrometry is considered to be a universal method with high specificity and high sensitivity and has been widely used. At present, mass spectrometry technology is used for mass analysis of substances at home and abroad. Mass spectrometers are one of the most promising scientific instruments in today's scientific instruments, and quadrupole mass spectrometers (also known as quadrupole mass spectrometers) are currently the most mature small O...
