Description

Technical Field

[0001] The utility model relates to the field of intelligent sample ionization processing devices for mass spectrometers, and more specifically, to an intelligent sample ionization processing device for mass spectrometers. Background Art

[0002] In the Chinese patent document with patent publication number CN212134222U, its authorization publication date is December 11, 2020;

[0003] It states in the background technology: “Mass spectrometry is an instrument for separating and detecting different isotopes, and a protein quantitative sampling device for mass spectrometry is a device for completing protein quantitative sampling;

[0004] The existing protein quantitative sampling device for mass spectrometry detection has certain drawbacks when used. First, the quantitative sampling effect is not good enough, and the amount of liquid protein cannot be increased or decreased according to the actual situation. Second, the fixing effect of the sampling device is not good enough, and the use effect is poor. Therefore, we propose a protein quantitative sampling device for mass spectrometry detection";

[0005] The utility model discloses a protein quantitative sampling device for mass spectrometry detection, comprising a device body, a base is arranged at the lower end of the device body, a fixed pillar is arranged at the center of the upper outer surface of the base, a weight block is arranged on the outer surface of the fixed pillar near the lower edge, a top plate is arranged on the upper outer surface of the fixed pillar, a convex magnetic column is arranged on the lower outer surface of the top plate, a concave magnetic column is arranged on the lower outer surface of the convex magnetic column, a threaded column is arranged on the lower outer surface of the concave magnetic column, a sampling barrel is arranged on the outer surface of the threaded column, a scale is arranged on the outer surface of the sampling barrel, and a sampling head is arranged on the lower outer surface of the sampling barrel. The protein quantitative sampling device for mass spectrometry detection described in the utility model can fix the device well and is not easy to fall over, and at the same time, the quantitative sampling effect of protein is good and the use effect is good;

[0006] However, as described in the above conventional patent documents, the existing protein quantitative sampling device for mass spectrometry detection has certain drawbacks when used, such as the quantitative sampling effect is not good enough, and the amount of liquid protein cannot be increased or decreased according to the actual situation. At the same time, it can be seen from the drawings of the above patent documents that the protein quantitative sampling device for mass spectrometry detection is difficult to adjust in any direction to achieve a better sampling effect.

[0007] After sampling is completed, we often need to conduct testing and analysis. However, the current sampling equipment is often isolated, that is, sampling and testing and analysis are not in the same area. This requires the sampling personnel to send the sample for testing after the test is completed, and then issue a test and analysis report, which increases the overall operation time;

[0008] Its prior art patent states that its authorization announcement number CN116190197A discloses a sample intelligent ionization processing device for a mass spectrometer, which relates to the technical field of sample intelligent ionization processing, and includes a fixed bottom plate; an X-axis motion mechanism; a Z-axis motion mechanism, which is installed on the top plate; a Y-axis motion mechanism, which is installed on the Z-axis motion mechanism; and a quantitative suction sampling mechanism, which is installed on the Y-axis motion mechanism. In the present invention, the protein sample is placed in the detection table mechanism, and the quantitative suction sampling mechanism can perform sampling in any direction under the mutual cooperation between the X-axis motion mechanism, the Z-axis motion mechanism and the Y-axis motion mechanism, and the ion analyzer can transmit data to the terminal of the inspection center through the wireless communication module in the controller, and the inspectors in the background compare the spectrum obtained after the test with the standard spectrum, and display the results to the inspectors in the form of charts, thereby shortening the overall time from sampling to detection and analysis;

[0009] The above patent adopts multiple motors to carry out multi-axis linkage control for mobile sampling, and the control mechanism is complex. The sampling tube and the waste tube are aligned and sampled by translational movement, which is complex and inconvenient to use. Utility Model Content
