Abstract

A negative-pressure chromatographic equipment is composed of cylindrical main body, the quick-unlocked locking top conic closure head with negative pressure port connected to negative pressure pump via valve and vapour-liquid separator, conic top fastener for said conic top closure head, the quickly-unlocked locking bottom conic closure head with liquid inlet connected to liquid outlet of three-way value via liquid inlet tube, and conic bottom fastener for said conic bottom closure head. Its advantages are high separation efficiency and speed, less consumption of solvent and energy, and no noise and pollution.

Description

Technical field [0001] The invention belongs to an extraction, separation and purification device in the fields of chemical industry and pharmacy, and in particular relates to a negative pressure chromatography device for separation and purification of effective components of natural products. Background technique [0002] Chromatography is a method of separating different substances using different equilibrium distribution coefficients in two phases (one is a stationary stationary phase and the other is a flowing mobile phase). The chromatography process is based on the sample group In the two incompatible phases, the separation is achieved due to the difference in the distribution coefficient. According to the state of the two phases, there are liquid chromatography and gas chromatography. According to the mechanism of the chromatography process, there are adsorption chromatography, partition chromatography, size exclusion chromatography and ion exchange chromatography. Ac...
