Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a composite tandem mass spectrometer with convenient control and purification treatment, including a tandem mass spectrometer 1 and a purification guide structure 2. The tandem mass spectrometer 1 is set at the side end of the purification guide structure 2. The tandem mass spectrometer 1 can realize multi-stage mass spectrometry analysis by connecting multiple mass analyzers in series and combining them with a collision activation chamber. Its core is to ionize the sample through an ionization source, and then the ions enter the first-stage mass analyzer for separation. The selected ions collide and break with inert gas in the collision chamber, and the resulting daughter ions enter the second-stage mass analyzer for detection. Thus, after the gas in the detection tube 5 is detected by the tandem mass spectrometer 1, it can be introduced into the second tandem mass spectrometer 1 and the purification guide structure 2 for multi-stage detection and analysis.

[0021] The purification guide structure 2 is used for gas introduction and discharge. It includes an introduction component 3 and a discharge component 4. The introduction component 3 introduces gas, which is electrically connected to the tandem mass spectrometer 1 via a detection cylinder 5 for detection. The detection cylinder 5 is connected to the discharge component 4 for exhaust treatment. A high-pressure gas seat 9 is connected to the introduction pipe 7 via a first solenoid valve 10. The introduction pipe 7 is connected to the detection cylinder 5 via a connecting pipe 6, introducing pressurized gas into the detection cylinder 5. Residual gas is then discharged through the discharge component 4. By installing the purification guide structure 2, gas can be introduced and discharged simultaneously. The gas is analyzed by the cooperation of the tandem mass spectrometer 1 and the detection tube 5. The gas is then discharged through the discharge component 4. The high-pressure gas seat 9 is controlled by the first solenoid valve 10 to open, so that the gas in the high-pressure gas seat 9 is introduced into the inlet tube 7 through the first solenoid valve 10, and then guided into the detection tube 5 through the connecting tube 6. The residual gas is introduced into the discharge tube 13 through the detection tube 5, and then guided into the double-pass tube 16 through the U-shaped tube 14 and the connecting tube 15, and finally discharged through the discharge tube 17. The first pressure gauge 8 and the second pressure gauge 18 are used for monitoring the internal pressure.

[0022] The inlet component 3 includes a detection cylinder 5, a connecting pipe 6, and an inlet pipe 7. The side end of the detection cylinder 5 is connected to the connecting pipe 6, and the side end of the connecting pipe 6 is connected to the inlet pipe 7. A first pressure gauge 8 is installed on the inlet pipe 7. The rear end of the inlet pipe 7 is connected to a connecting conduit 12 through a second solenoid valve 11. The side end of the inlet pipe 7 is connected to a high-pressure gas seat 9 through a first solenoid valve 10.

[0023] The discharge component 4 includes a discharge pipe 13, a U-shaped pipe 14, and a connecting pipe 15. The discharge pipe 13 is connected to the connecting pipe 15 via the U-shaped pipe 14. A double-pass pipe 16 is connected to the side of the connecting pipe 15. A second pressure gauge 18 is installed on the double-pass pipe 16. A discharge pipe 17 is connected to the side of the double-pass pipe 16. The gas to be detected is introduced through the connecting conduit 12, guided by the second solenoid valve 11 to the inlet pipe 7. At this time, the first pressure gauge 8 performs pressure detection. The gas is then guided through the inlet pipe 7 to the connecting pipe 6, and then connected to the detection cylinder 5. Finally, the gas is discharged through the connecting pipe 15. Inside the outlet tube 13, the gas is guided and discharged through the U-shaped tube 14 and the connecting tube 15, and finally discharged from the inside of the tandem mass spectrometer 1 and the purification and discharge structure 2 through the double-pass tube 16 and the discharge tube 17. The second pressure gauge 18 is set to detect the discharge pressure. After the detection is completed, the first solenoid valve 10 needs to be opened so that the compressed gas in the high-pressure gas seat 9 can be conducted to the inlet tube 7 through the first solenoid valve 10, and then transmitted through the connecting tube 6 and the detection cylinder 5. After that, it is discharged through the outlet tube 13, the U-shaped tube 14, the connecting tube 15, the double-pass tube 16 and the discharge tube 17, thereby venting the residual gas and facilitating subsequent experimental work.

[0024] The discharge tube 13 is connected to the bottom of the detection tube 5, and the detection tube 5 is electrically connected to the tandem mass spectrometer 1.

[0025] The tandem mass spectrometer 1 is a TQ-GC01 model.

[0026] The detection tube 5 is built into the tandem mass spectrometer 1, and the high-pressure gas seat 9 adopts a replaceable design.

[0027] Working principle: When needed, the user introduces the gas to be detected through the connecting conduit 12, which then guides it to the inlet pipe 7 via the second solenoid valve 11. At this time, the first pressure gauge 8 detects the pressure. The gas is then guided through the inlet pipe 7 to the connecting pipe 6, and then connected to the detection cylinder 5. The gas is then introduced into the discharge pipe 13 through the connecting pipe 15, and discharged through the U-shaped pipe 14 and the connecting pipe 15. Finally, it is discharged from the tandem mass spectrometer 1 and the purification and discharge structure 2 through the double-pass pipe 16 and the discharge pipe 17. The second pressure gauge 18 is set up to detect the discharge pressure. After the detection is completed, the first solenoid valve 10 needs to be opened so that the compressed gas in the high-pressure gas seat 9 can be conducted to the inlet pipe 7 through the first solenoid valve 10, and then transmitted through the connecting pipe 6 and the detection cylinder 5. After that, it is discharged through the discharge pipe 13, U-shaped pipe 14, connecting pipe 15, double-pass pipe 16 and discharge pipe 17, thereby venting the residual gas and facilitating subsequent experimental work. The discharge pipe 17 can be connected to the external purifier for subsequent continuous purification treatment to complete the work.
