Description

Technical Field

[0001] The present application relates to an electrospray ion source, and in particular to a state monitoring device for an electrospray ion source. Background Art

[0002] The function of the electrospray ion source is to convert the molecules in the sample solution to be analyzed into gaseous ions, which enables various compounds such as proteins, peptides, and drug molecules to enter analytical instruments such as mass spectrometers in the form of ions for mass analysis, which helps to determine the mass and structure of the molecules. It is widely used in the ionization process of compounds in the fields of chemical analysis and biological analysis. It is a key part connecting samples and analytical instruments, and plays an important role in the analysis and identification of the components of complex mixtures. At present, it is necessary to use infrared temperature sensors to detect the temperature of the outside of the electrospray ion source during its use. First of all, this detection method is non-invasive. The internal structure of the electrospray ion source is delicate and complex. The infrared temperature sensor will not interfere with the precise structure inside the device and the normal ionization workflow when measuring from the outside. Secondly, it can monitor the status of the device in real time. The temperature of the device will change due to various factors. These changes can be grasped in time through the external temperature detection. Once a fault causes an abnormal temperature increase, it can be quickly detected. Moreover, this helps to ensure the performance and life of the device. The appropriate temperature is crucial to the performance of the device. Excessive temperature will accelerate the aging of components and affect accuracy and stability. Infrared temperature sensor detection can ensure that the device operates in a safe temperature range and reduce maintenance costs. Finally, this temperature detection can ensure the accuracy of the experiment or analysis process. Because temperature affects the sample ionization efficiency and ion transmission characteristics, detecting the external temperature can effectively control the experimental temperature conditions and improve the accuracy and repeatability of the experimental results. However, during general application, most of the existing infrared temperature sensors are arranged on one side of the ion source. This layout enables the infrared temperature sensor to only detect the temperature of one side of the ion source. However, during the operation of the ion source equipment, the temperature of the entire device is usually different. Due to the fixed design of the infrared temperature sensor, it can usually only monitor the temperature of a specific point on one side. This temperature monitoring method has obvious limitations and cannot comprehensively and stably monitor the temperature status of various positions on the surface of the ion source equipment. In actual applications, there will inevitably be blind spots for status monitoring, and it is difficult to accurately reflect the overall temperature status of the ion source equipment. Obviously, this situation makes the existing infrared temperature sensor have certain defects and deficiencies during use, and cannot meet the needs of accurate temperature monitoring of the ion source equipment. Therefore, in order to better ensure the safe operation of the ion source equipment and improve the accuracy of temperature monitoring, it is urgent to improve the existing application method of infrared temperature sensors.

This design enables the slip ring 63 to slide stably in the annular rail 62, preventing the slip ring 63 from slipping or deflecting during movement, thereby ensuring the normal operation of the rotating mechanism 6, and further providing a reliable structural foundation for the monitoring mechanism 8 to perform all-round rotation monitoring around the ion source body 4.

[0024] The implementation principle of the state monitoring device of an electrospray ion source in the embodiment of the present application is as follows: by setting a rotating mechanism 6 and a monitoring mechanism 8, the device can start the infrared temperature sensor 83 at the outer end of the connecting rod 82 on the fixed plate 732 in the monitoring mechanism 8 during actual use to monitor the temperature of the outer side of the ion source body 4. During the temperature monitoring process, the first motor 612 is started to run, and the first motor 612 can drive the first gear 613 on the mounting seat 611 to rotate. Since the first gear 613 is meshed with the gear ring 64, as the first gear 613 rotates, it can synchronously drive the gear ring 64 meshed with it to rotate. The gear ring 64 is fixedly connected to the top of the slip ring 63. When the gear ring 64 is driven, the slip ring 63 can be synchronously driven to rotate on the inner side of the annular rail 62. The slip ring 63 and the annular rail 62 slide and engage with each other, so that they can stably rotate around the outer side of the ion source body 4. With the rotation of the gear ring 64 and the slip ring 63, the infrared temperature sensor 83 can be synchronously driven to rotate around the outer side of the ion source body 4, thereby realizing 360-degree all-round temperature monitoring of the outer side of the ion source body 4. This design can effectively reduce the monitoring blind spot, greatly improve the temperature monitoring effect, and make it possible to more accurately reflect the overall temperature condition of the ion source equipment. By setting the adjustment mechanism 7, during the use of the device, when the temperature of the ion source body 4 is detected by the infrared temperature sensor 83, the second motor 714 can be started to run, and the second motor 714 can drive the screw rod 712 inside the transverse guide rail to rotate, thereby driving the sliding block 713 inside the transverse guide rail 711 to slide laterally, and the lateral sliding of the sliding block 713 can assist in driving the longitudinal guide rail 72 and the longitudinal module 73 inside it to approach the ion source body 4 or move away from the ion source body 4. By adjusting the distance between the longitudinal module 73 and the ion source body 4, the distance between the infrared temperature sensor 83 and the ion source body 4 can be adjusted, thereby improving the convenience of its overall detection application and installation application. In addition, during the detection, the third motor can be started 7333 is running, and the third motor 7333 can drive the second gear 7334 to rotate. Since the second gear 7334 is meshingly connected with the rack 7332, as the second gear 7334 rotates, the second gear 7334 can be caused to roll and displace on the rack 7332. The displacement of the second gear 7334 can drive the slider 731 to move up and down. The up and down movement of the slider 731 can drive the fixed plate 732 and the monitoring mechanism 8 thereon to move up and down. It can be seen that the device can adjust the infrared temperature sensor 83 away from or close to the ion source body 4, and perform rotation adjustment at the same time, and then cooperate with the up and down adjustment, so as to perform all-round and non-dead-angle temperature monitoring of the outer surface of the ion source, thereby reflecting the overall temperature condition of the ion source equipment to the greatest extent.

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.
