Description

TECHNICAL FIELD

[0002] In some mass spectrometers, especially in gas chromatography - mass spectrometer, the carrier gas transmission pipeline from the carrier gas cylinder to the mass spectrometer can partially adopt the hose. The material such as polytetrafluoroethylene pipe is usually selected, which has the characteristics of good chemical stability, low friction coefficient, can adapt to different gas transmission requirements, and ensures that the carrier gas is stably and cleanly transported to the mass spectrometer.

[0003] The main role of the carrier gas is to carry the sample through the chromatographic column for separation. If the carrier gas flow is unbalanced, the retention time of the sample in the chromatographic column will change, and different components that can be effectively separated according to the normal flow rate may not be well separated due to abnormal flow rate, resulting in phenomena such as chromatographic peak broadening, tailing or overlapping, ultimately affecting the qualitative and quantitative analysis results of each component by mass spectrometry. For example, two material peaks that can be clearly distinguished may overlap together due to the carrier gas flow problem, making it difficult to accurately determine the type and content of the material.

[0004] And one of the main reasons for the unbalanced carrier gas flow is that the carrier gas transmission pipeline is folded or deformed when bending, which changes the gas flow in the pipeline and affects the balance of gas flow.

DETAILED DESCRIPTION

[0025] The specific embodiment is a pipe support structure for a mass spectrometer, the structural diagram of which is shown in Figures 1-6 , comprising a mass spectrometer main body 1 and a slide rail 2, which is detachably connected to the side wall of the mass spectrometer main body 1, and a sliding block 3 is slidingly connected to the side wall of the slide rail 2, and a mounting plate 4 is fixedly connected to the side wall of the sliding block 3, the mounting plate 4 is U-shaped, two support plates 5 are fixedly connected to the inner side walls of the mounting plate 4 near the two ends, and pressing assemblies are arranged on the upper and lower side walls of the mounting plate 4.

[0026] As shown in Figure 4 and Figure 5 , the pressing assembly comprises a screw 6 threadedly connected to the side wall of the mounting plate 4, the screw 6 is rotatably connected to a pressing plate 7 near the center of the mounting plate 4, the other end of the screw 6 is hexagonal in structure, and the opposite side wall of the pressing plate 7 is provided with a anti-falling assembly.

[0027] Among them, when the carrier gas pipeline passes through the inner side of the mounting plate 4, the two support plates 5 on both sides will support the carrier gas pipeline, and the position of the carrier gas pipeline between the two support plates 5 is prone to warping, if the carrier gas pipeline warps, the contact position with the support plate 5 will increase in force, thus increasing the deformation of the carrier gas pipeline, and by pressing the position of the carrier gas pipeline inside the mounting plate 4, the above problem can be avoided, thereby ensuring the balance of the flow inside the carrier gas pipeline.

[0028] As shown in Figure 5 , the anti-falling assembly comprises a groove 8 opened in the end face of the pressing plate 7, a baffle 9 is arranged in the groove 8, the side wall of the baffle 9 is fixedly connected with a rotating shaft 10, the other end of the rotating shaft 10 is rotatably connected with the side wall of the groove 8, and the side wall of the rotating shaft 10 is assembled with a torsional spring 11.

[0029] Specifically, in order to further increase the stability, the baffle 9 is arranged on the pressing plate 7, and the torsional spring 11 can shield the carrier gas pipeline by using the force, thereby avoiding the disengagement of the carrier gas pipeline inside the mounting plate 4, and effectively improving the use effect.

[0030] As shown in Figure 4 and Figure 6 , the side wall of the sliding block 3 is threadedly connected with a stud 12, the side wall of the stud 12 is fixedly connected with a handle 13, and one end of the stud 12 abuts against the side wall of the slide rail 2.

[0031] When the position of the mounting plate 4 needs to be adjusted, the handle 13 is rotated to drive the stud 12 to rotate, so that the stud 12 is disengaged from the slide rail 2, so that the sliding block 3 can slide on the slide rail 2, and after the sliding block 3 is moved to a suitable position, the handle 13 is reversely rotated to lock the sliding block 3, so as to adjust the number of the sliding blocks 3, and in addition, a plurality of sliding blocks 3 can be arranged on the same slide rail 2, so as to position and support a plurality of carrier gas pipes.

[0032] As shown in Figure 3 , the slide rail 2 is fixedly connected with double-sided adhesive tape 14 and a magnetic sheet 15 on the side wall away from the mounting plate 4. A suitable mounting mode can be selected according to actual needs to achieve the purpose of being detachable.

[0033] As shown in Figure 4 , the support plate 5 is in an arc-shaped structure. The arc-shaped structure of the support plate 5 can reduce the phenomenon of folding or deformation of the carrier gas pipe caused by sudden bending at the end face position of the support plate 5, thereby improving the flow uniformity.

[0034] Working principle: first, according to the position of the carrier gas pipe, the slide rail 2 is fixed on the mass spectrometer main body 1 at a suitable position through the double-sided adhesive tape 14 or the magnetic sheet 15, then the two side baffles 9 are flipped outward, the torsional spring 11 is compressed, then the carrier gas pipe is placed inside the mounting plate 4 and on the support plate 5, the arc-shaped structure of the support plate 5 can avoid excessive bending of the carrier gas pipe, in order to further improve the stability of the carrier gas pipe, the two side screws 6 are rotated to drive the pressing plate 7 to extrude the carrier gas pipe, which plays a fixing role and also achieves the purpose of shaping, thereby ensuring the flow uniformity in the carrier gas pipe.

[0035] All the technical features in the embodiment can be freely combined according to actual needs.

[0036] The above embodiment is a preferred implementation scheme of the present application, and in addition, the present application can be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
