Abstract

The invention relates to the technical field of gas chromatographs, and discloses a gas chromatography mass spectrometry analytical instrument which comprises an analytical instrument body, a heat dissipation device is arranged in the analytical instrument body, the heat dissipation device comprises a connecting frame, a communicating groove is formed in the connecting frame, a heat dissipation net is arranged in the connecting frame, and the communicating groove is communicated with the heat dissipation net. According to the heat dissipation device, air in the air bag is heated and expanded to drive the connecting rod to be separated from the transverse plate, the transverse plate pulls the heat dissipation net through the elastic rope under the action of gravity, and the heat dissipation net can be vibrated to remove dust on the surface of the heat dissipation net; when a transverse plate deflects, a sliding block is pulled through a connecting rope to slide along a sliding groove, the sliding block extrudes and drives a connecting plate to deflect and then knocks the heat dissipation net, and therefore dust on the surface of the heat dissipation net can be removed in an auxiliary mode, and cleaning of the heat dissipation net is completed.

Description

technical field [0001] The invention relates to the technical field of gas chromatography, in particular to a gas chromatography mass spectrometry analysis instrument and an analysis method. Background technique [0002] Traditionally, the gas chromatographic analysis device is based on the system composed of different substances in the stationary phase and the mobile phase, that is, the chromatographic column has different distribution coefficients to separate the components of the sample gas to be tested, and then use a mass spectrometer to separate each component. The chromatographic peaks of the constituent gases are converted into electrical signals, which are converted into voltage or current output by an electronic amplifier. Gas chromatography, gas chromatography mass spectrometry or single mass spectrometry are generally used for on-site rapid emergency monitoring of various environmental volatile and semi-volatile organic compounds such as gases and liquids.
