Chromatograph

Abstract

The present invention relates to the field of chromatographs, and in particular to a chromatograph, comprising a chromatograph case, a top plate, a sample placement mechanism,a dustproof mechanism, support legs, a moving mechanism, and hand wheels, wherein top of the chromatograph case is fixedly provided with the top plate, and one side of the chromatograph case is provided with the sample placement mechanism for storing samples. When the chromatograph is in use, and when the chromatographic instrument needs to be placed stably, the hand wheels are rotated to drive gears to rotate, and gear plates are driven to move upward during rotation of the gears, thereby moving wheels are driven to move upward, so that the moving wheels are received inside the support legs, so that the supporting legs contact the ground, the support legs are used for support, to achieve stable positioning during use, and in the same time, fixed plates are driven to move downwards by rotation of the gears, so that dustproof plates leave side of heat dissipation holes, and so that the heat dissipation holes can be used for heat dissipation, and stable positioning and synchronous heat dissipation can be achieved.

Description

technical field [0001] The invention relates to the field of chromatographs, in particular to a chromatograph. Background technique [0002] Chromatograph is a device for chromatographic separation and analysis, including sample introduction system, detection system, recording and data processing system, temperature control system and mobile phase control system, etc. Modern chromatograph has stability, sensitivity, versatility and It has the characteristics of high degree of automation, such as gas chromatography, liquid chromatography and gel chromatography. These chromatography are widely used in the analysis of certain content of chemical products and polymer materials. Gel chromatography can also determine the content of polymer materials. Molecular weight and its distribution, the earliest application of chromatography is used to separate plant pigments, the method is as follows: put calcium carbonate in a glass tube, pour petroleum ether containing plant pigments (pla...

AI Technical Summary

Problems solved by technology

[0003] Gas chromatograph refers to a chromatographic analysis instrument that uses gas as the mobile phase. The principle is mainly to use the differences in the boiling point, polarity and adsorption properties of substances to separate the mixture. In the chromatographic column, the column contains a liquid or solid stationary phase, and each component in the sample tends to form a distribution or adsorption equilibrium between the mobile phase and the stationary phase. With the flow of the carrier gas, the sample components are repeatedly in motion. For multiple distributions or adsorption and desorption, the components with high concentration in the carrier gas flow out of the column first, and the components with high concentration in the stationary phase flow out after distribution. Traditional gas chromatographs are not easy to carry and require users to Holding and moving, however, consumes too much manpower and material resources and is not convenient for users to use. If a moving mechanism such as universal wheels is installed, the problem of movement is solved, but there is also the problem of unstable placement when using universal wheels for support, especially for outdoor environments If it is used under the environment, once the outdoor ground is uneven, it will be placed unstable, which will not be conducive to the injection of the sample, and it will easily cause the problem of liquid leakage when the sample is injected, and the syringe is not easy to place when injecting the sample. , outdoors, most of them are placed by hand, which is not conducive to sampling and analysis, and is not easy to take, resulting in poor use effect, and the traditional traditional gas chromatograph has the problem of incompatibility with heat dissipation and dust removal
