The ionization ultraviolet lamp is a single photon ultraviolet light emission source, mainly comprising a lamp body, an optical window and electrodes, wherein the lamp is vacuumized and then filled with inert gas, and ultraviolet rays with the luminous energy of 8-12eV (about 150-110nm) are obtained by excitation of direct current high voltage or radio frequency high voltage; the glass optical window is made of magnesium fluoride material and can transmit ultraviolet light, and the transmission optical path of the ultraviolet light in the air is generally within 1 cm; organic matters in the air environment outside the glass optical window (generally, the ionization energy is 7-10eV, and for the organic matters with the ionization energy larger than 10eV, a dopant acetone with low ionization energy can be provided to assist ionization) are ionized into ions by ultraviolet light for analysis.
The assembly of the ionization ultraviolet lamp aims at realizing the sealing between the glass optical window and the cavity of the ion transfer tube, particularly the metal repelling electrode, a sealing groove and a sealing ring are usually arranged on the metal repelling electrode, and then the edge between the glass optical window and the ionization ultraviolet lamp body is pushed by a glass optical window limiting groove on a lamp sleeve with external threads, so that the sealing between the glass optical window and the metal repelling electrode is realized by the sealing ring. In actual operation, two problems occur, namely, the sealing ring is aged and thinned, so that the glass optical window is broken or damaged when contacting with a sealing groove of a metal repelling electrode; secondly, the glass optical window limiting groove on the lamp sleeve has overlarge ejection force, so that the glass optical window is damaged or even separated, and the assembly reliability and the service life of the ionization ultraviolet lamp are seriously influenced.
Gajiayi et al invented a method for assembling an ultraviolet lamp in an ion mobility spectrometry device and an ion mobility spectrometry device (patent No. ZL201210049161.0), wherein the ultraviolet lamp is horizontally arranged at the front end of an ionization region of an ion mobility tube, and an ionization channel with the width of 4mm is reserved in front of an ultraviolet window, so that the ionization region is kept complete and the movement direction of ions cannot be deviated when the ions pass through the ionization region.

The device has small volume and compact structure, and is suitable for ionization excitation of a vacuum ultraviolet lamp ionization source in an ion mobility spectrometer.
The invention discloses an ion migration tube (patent No. ZL202023012576.X) capable of prolonging the service life of a photoionization source, and discloses an ion migration tube capable of prolonging the service life of the photoionization source, which comprises a vacuum ultraviolet lamp and an anti-reflection glass window, wherein the two components are coaxially arranged, ultraviolet light generated by the vacuum ultraviolet lamp is vertically emitted to the surface of the anti-reflection glass window, the vacuum ultraviolet lamp is isolated from an ionization region cavity of the migration tube by the anti-reflection glass window, and the anti-reflection glass is easy to replace, so that the effect of reducing the pollution of the vacuum ultraviolet lamp window is achieved.
The invention discloses an integrated vacuum ultraviolet lamp ionization source differential ion mobility spectrometer (patent number ZL201611041188.x) invented by Liyang et al, which comprises a differential ion mobility spectrum, an ultraviolet lamp ionization source and a fixed groove, wherein all carrier gas between two parallel migration polar plates of the differential ion mobility spectrum horizontally enters the migration polar plates through a gas inlet, and all gas is completely discharged through a horizontal gas outlet, so that the sealing problem of the differential ion mobility spectrum is solved, the gas flow of the differential ion mobility spectrum is stable, and the detection reliability is ensured.
