Abstract

The invention discloses a chromatographic analysis device, relates to the technical field of experimental instruments, and aims to solve the problem that the elution effect of a to-be-detected sampleis influenced due to the fact that the dissolving amounts of various gases in eluent can be changed along with the change of the environment temperature. According to the technical scheme, the deviceis characterized by comprising a heat preservation box, and a cylindrical workbench is arranged in the heat preservation box; and the workbench is divided into an upper layer and a lower layer, a motor is arranged in the lower layer, and an annular rail is arranged at the top of the workbench lower layer. A chute slidably connected with the rail is formed in the bottom of the workbench upper layer; racks arranged in the circumferential direction of the workbench are arranged on the inner wall of the bottom of the workbench upper layer. The output end of the motor is connected with a gear meshed with the circular rack, and a heating resistor is arranged in the workbench; a cover body used for sealing the opening is arranged on the chromatographic bottle, two hooks are symmetrically arrangedon the cover body, and two fixing rings matched with the corresponding hooks in a clamped and embedded mode are oppositely arranged on the inner wall of the heat preservation box. According to the invention, the effect of keeping the temperature of the test environment stable is achieved.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a chromatographic analysis device. Background technique [0002] A chromatographic bottle is used in the existing chromatographic analysis sampling device system, which usually includes a bottle mouth and a bottle body in addition to the bottle cap. The sample is loaded from the mouth of the bottle, and the sample needle is taken from the mouth of the bottle. Such chromatographic vials can only be used to store a fixed amount of samples, for example, 1ml, 5ml, etc. volumes of samples are loaded at one time, and then taken. The liquid chromatography analysis device injects the eluent together with the sample to be tested into the chromatographic column to elute the target substance in the sample to be tested for determination. [0003] However, the dissolved amount of various gases in the eluent will change with the change of the ambient temperature, which will ...
