Description

Technical Field

[0001] The present application relates to the technical field of gas flow control of ion source equipment, and in particular to a collision gas flow state control device. Background Art

[0002] Electrospray ion source is an important ionization method in mass spectrometer. It applies high voltage to the tip of quartz capillary containing sample solution to form charged droplets. After assisted desolvation, the droplets "burst" to produce single ions as the solvent evaporates. This ion source can generate multi-charged ions from large-mass organic molecules, expanding the molecular weight range that can be analyzed by mass spectrometry. It is especially suitable for analyzing highly polar large-molecule organic compounds such as drugs, peptides, sugars, proteins and nucleic acids. In addition, the ionization process is not easy to produce fragment peaks, which is conducive to molecular weight confirmation. However, it also has limitations. It requires that the sample can form ions in the solution. The type and concentration of buffer salts in the mobile phase affect the sensitivity. There is matrix suppression phenomenon. The collision gas flow of the electrospray ion source is a neutral gas flow provided by an external gas source (such as nitrogen, argon, etc.), which is introduced into the collision area of ​​the ion source through a pipeline and valve system. Its functions include: first, assisting ion desolvation. After the electrospray generates charged droplets, the ions collide with the neutral gas molecules in the collision gas flow to accelerate the evaporation of the solvent and improve the ionization and transmission efficiency; second, it is used for ion focusing and transmission. The ion motion trajectory is changed by collision, and the pressure and flow gradients are used to effectively guide the ions to the entrance of the mass analyzer to reduce ion diffusion and loss; third, it is used to regulate ion energy. Energy exchange occurs when ions collide with gas molecules. The kinetic energy of the ions can be adjusted by controlling the gas flow parameters. It also affects the analysis results, can improve the mass resolution, make the ions more regular before entering the mass analyzer, reduce the ion beam width and energy dispersion, and help to distinguish ions with different mass-to-charge ratios. At the same time, it will also affect the fragmentation pattern. Different gas flow conditions can induce ions to produce different fragment ions, which is very important for analyzing the structure of compounds. At present, the flow state control of the electrospray ion source collision gas is often assisted by a flow pressure regulating valve. Based on the relationship between flow and pressure, the pressure difference in the pipeline is adjusted by changing the valve opening to control the collision gas flow. It has the advantages of high precision control, wide adjustment range, and adaptability to a variety of gases. However, the influence of different gas characteristics and the coordination with other equipment, such as gas purity requirements, coordination with sensors, and system integration, need to be considered during use. The existing pressure regulating valve is usually installed and fixed by a plurality of bolts and a flange during use. It is difficult to disassemble the pressure regulating valve when it needs to be repaired, and it is also troublesome to install. The Chinese patent with the announcement number "CN210687143U" discloses a new self-operated pressure regulating valve, which includes a diaphragm box and a connecting plate, wherein the diaphragm box is installed on the outer wall of the upper end of the connecting plate, and the connecting plates are provided with two. The utility model is a new self-operated pressure regulating valve that is improved and innovated on the basis of the existing self-operated pressure regulating valve, so that the practical performance of the self-operated pressure regulating valve in actual work is greatly increased, the internal cleanliness of the regulating valve is ensured, and the smooth progress of the regulating work is ensured. The utility model is a new self-operated pressure regulating valve that newly adds components such as a flow pipe, a one-way cover, a first flow hole, a second flow hole, a one-way sheet, a threaded rod and a filter screen on the existing self-operated pressure regulating valve, and the shape of the newly added flow pipe is adjusted through the one-way sheet and the one-way cover according to the flow direction of the fluid, and the filter screen connected to the flow pipe is used to filter the fluid to prevent the regulating valve from being blocked; During actual application, the above-mentioned pressure regulating valve is obviously connected by flanges. During its specific application process, a filter is set inside to play an auxiliary filtering role. However, during use, the impurities filtered out by the filter will inevitably adhere to the surface of the filter. With the continuous use of the pressure regulating valve, this situation will cause the filter to be gradually blocked. Once the filter is blocked, it will affect the gas flow rate inside the pressure regulating valve during use. After the gas flow rate is affected, it will directly affect the normal use and operation of the electrospray ion source equipment; if the filter needs to be cleaned, the operation is extremely cumbersome and inconvenient. Overall, the cleaning and maintenance during subsequent use is relatively time-consuming. Obviously, this pressure regulating valve has many cumbersome and inconvenient aspects during use. Therefore, in order to improve its use efficiency and convenience and meet the stable operation requirements of the electrospray ion source equipment, it is urgent to improve it.

[0026] The implementation principle of a collision gas flow state control device according to an embodiment of the present application is as follows: by setting a mounting mechanism 1, during actual use of the device, the mounting plate 11 can be firmly fixed in a suitable position by means of bolts. After the mounting plate 11 is installed, the flow pressure regulating valve 4 can be placed between the inner sides of the two clamping connecting mechanisms. At this time, the docking plug 22 is accurately located on the inner side of the docking sleeve 23. By gently pulling the pull ring 166, the limit rod 165 can be driven to disengage from the limit hole 162. In this process, the limit spring 163 The adjusting plate 133 is in the stretched state, and then the adjusting plate 133 can be twisted to rotate. The rotation of the adjusting plate 133 will drive the screw rod 131 inside the fixed track 12 to rotate. The rotation of the screw rod 131 can drive the sliding block 132 to slide smoothly inside the fixed track 12. By adjusting the sliding position of the sliding block 132, the clamping connecting components 2 can be driven to move relative to each other. At this time, the side connecting rod 21 will drive the docking sleeve 23 to be accurately sleeved to the outside of the docking plug 22. Because the docking sleeve 23 and the docking plug 22 are sleeved with each other, and the inner sides thereof are A sealing gasket ring 31 is arranged between the butt sleeve 23 and the butt plug 22, which greatly improves the sealing performance of the butt sleeve 23 and the butt plug 22. In this way, the flow pressure regulating valve 4 can be installed assisted. When the operation is completed, the pull ring 166 is loosened, and the limit spring 163 will quickly reset, driving the end of the limit rod 165 to be inserted into the inner side of the limit hole 162 again. Through the mutual limiting effect of the limit rod 165 and the limit hole 162, the adjusting disk 133 at the end of the fixed screw rod 131 can be assisted to be clamped. When the flow pressure regulating valve 4 is installed, it can be The connecting flange 26 is connected to the pipeline of the ion source device to complete the connection installation. During use, the flow control valve can be used to adaptively adjust the collision gas flow state of the ion source device according to actual needs. When disassembly is required, it is only necessary to pull the pull ring 166 again to drive the limit rod 165 out of the limit hole 162, and then adjust the adjustment disk 133 to rotate, so that the flow pressure regulating valve 4 can be quickly disassembled and assembled. It can be seen that the device as a whole is easy to quickly disassemble and overhaul, which greatly improves the overall convenience of use of the device. By setting the filtering mechanism 3, during the use of the device, the sealing gasket ring 31 is located between the inner sides of the docking plug 22 and the docking sleeve 23. After the flow pressure regulating valve 4 is installed, it can be given extremely strong sealing performance. During use, when the collision airflow flows at high speed inside the pipeline of the ion source device, the conical wind wheel 334 can be strongly pushed by this high-speed flowing airflow, and the outer end of the conical wind wheel 334 is provided with a spiral extension wind wheel 335, which can increase the contact area between the conical wind wheel 334 and the high-speed collision airflow, thereby prompting the conical wind wheel 334 to be pushed, thereby driving the turntable 331 to rotate, and the rotation of the turntable 331 will drive the cleaning brush plate 333 on the connecting rod 332 to rotate, and the cleaning brush plate 333 continues to rotate along the inside of the filter screen cover 32, and is always tightly connected with the inner wall of the filter screen cover 32. In this way, It can play a very good cleaning role on the inner side of the filter screen cover 32. Since the filter screen cover 32 is set in a conical shape, this shape can further increase the filtering area, not only to maintain the speed of air circulation inside the pipe, but also the inner wall of the cone is set at an angle. Therefore, each time the brush is rubbed and cleaned, the filtered impurities can be guided downward and discharged, and then can enter the interior of the impurity storage groove 34. It can be seen that the filter screen cover 32 of the present device has an automatic cleaning function, which can effectively prevent impurities from adhering to the filter screen and affecting air circulation, greatly improving the stability of the flow pressure regulating valve 4 during the overall application period, and, in conjunction with the setting of the installation mechanism 1, it can quickly disassemble and assemble the filter mechanism 3, facilitate the removal and cleaning of the filter screen cover 32, and facilitate the detailed cleaning of the filter screen and the inside of the impurity storage groove 34, which brings great convenience to the use of the present device.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
