Chromatography device

Abstract

The invention relates to a chromatography device, comprising a mobile phase container, a pump, a sample injector, a chromatographic column, a detector and a recorder which are sequentially connected, wherein the chromatographic column comprises a column pipe, an inner lining pipe arranged in the column pipe, a column joint and a sealed filtering ring arranged at the column joint; the inner lining pipe is internally provided with a filling layer; the column pipe is connected with a fixed nut by means of the column joint; the detector is provided with a waste liquid bottle in a connecting way; the chromatographic column is arranged in a cuboid column temperature box; the column temperature box comprises a rectangular bottom plate and four side plates which are respectively and vertically connected with the four sides of the rectangular bottom plate, wherein the side plates are sequentially connected with one another. The chromatography device has the advantages of being good in sealing property, high in measurement accuracy and high in detection and analysis sensitivity.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and relates to a chromatographic instrument, in particular to a chromatographic device. Background technique [0002] At present, the application of chromatographic devices is becoming more and more extensive. It uses the difference in the distribution table of the mixture between liquid-solid or two immiscible liquids to separate the mixture first, and then analyze and identify it. Most of the existing chromatographic devices are easy to Leakage, low measurement accuracy, low sensitivity of detection and analysis, etc. Therefore, a chromatographic device that can solve the above problems is needed, so that it has good sealing performance, high measurement accuracy, high sensitivity of detection and analysis, and meets the needs of actual detection. Contents of the invention [0003] The purpose of the present invention is to provide a chromatographic device that solves the problems o...
