Description
Technical Field
The invention relates to the field of polishing tools of ion sources of chromatography-mass spectrometer, in particular to an ion source polishing head.
Background
The chromatograph-mass spectrometer is an analytical instrument widely applied to the fields of medicine, physics, chemistry, biology and the like, wherein the mobile phase of gas chromatography is inert gas (the mobile phase of liquid chromatography is liquid), and when a multi-component mixed sample enters a chromatographic column, the operating speeds of the components in the chromatographic column are different due to different adsorption forces of an adsorbent to the components. After a certain period of time, the components with weak adsorption capacity are easily desorbed and leave the chromatographic column first and enter the mass spectrum. The mass spectrum ionizes each component in the sample in an ion source to generate ions with different charge-mass ratios and positive charges, and the ions form an ion beam under the action of an accelerating electric field and enter a mass analyzer. In the mass analyzer, the mass is determined by dispersing the generated opposite velocities by an electric field and a magnetic field, and focusing them to obtain mass spectra. Because each substance has a unique mass spectrum, and the analyzed sample spectrum can know what substance is analyzed by comparing with the spectra in the spectrum library, the mass spectrum is more and more applied.
However, after the mass spectrometer is used for a period of time, the ion source is polluted, so that the analysis result is influenced, and the ion source needs to be cleaned in time. But dirt on the ion source is firmly attached, the traditional method is to dip a cotton swab in the prepared alumina powder to polish the ion source, and the method is time-consuming, wherein about 30 minutes is needed for polishing one ion source, and the dirt with strong adhesive force can be thoroughly polished only by repeatedly polishing for a longer time when the pollution is serious. For the experimenter with smaller strength, the grinding time is longer; secondly, the hand feels ache after polishing due to long-time force application.
