Chemical corrosion-free liquid chromatographic column tube

Abstract

The invention relates to a chemical corrosion-free liquid chromatographic column tube. A pump machine shelf is fixedly arranged in an inner threaded sleeve; a miniature vacuum degassing pump is clamped and fixedly arranged in the pump machine shelf; the bottom of a mobile-phase liquid storage tube is connected with the inner threaded sleeve in a screwing manner; a solvent dropping-in tube is inserted into the top of the mobile-phase liquid storage tube; the tail end of the solvent dropping-in tube is connected to the top of the pump machine shelf in the screwing manner; the top of the solventdropping-in tube is fixedly provided with a funnel tube in a running-through manner; an exploring tube seat is fixedly arranged in an outer threaded sleeve; a sample introduction exploring tube is arranged in the exploring tube seat in a socket manner. The chemical corrosion-free liquid chromatographic column tube, by adopting the technical means that a gas suction tube fitting of the miniature vacuum degassing pump is communicated with the sample introduction exploring tube, a gas exhaust tube fitting of the miniature vacuum degassing pump is communicated with the mobile-phase liquid storagetube, the inner wall of a base is fixedly provided with a tray tube, moreover, the base is screwed into the outer threaded sleeve, a sample tube is inserted into the base, the sample tube and the baseare sealed and fixed through a sealing plug and the top of the sample tube is abutted with the bottom of the exploring tube base, is used for realizing the production of the chemical corrosion-free liquid chromatographic column tube.

Description

technical field [0001] The invention relates to a chemical corrosion-free liquid chromatography column tube. Background technique [0002] Liquid chromatography is a kind of separation and analysis technique, which is characterized by using liquid as the mobile phase, and the stationary phase can have various forms, such as paper, thin plate and packed bed. In the process of chromatographic technology development. In order to distinguish the various methods, the respective nomenclature has been produced according to the form of the stationary phase, such as paper chromatography, thin-layer chromatography, and column liquid chromatography. The mobile phase of classical liquid chromatography flows through the chromatographic column slowly by gravity, so the particle size of the stationary phase cannot be too small (about 100 μm to 150 μm). The separated samples are collected by fractions and then analyzed, which makes the classical liquid chromatography not only have low sep...
