Abstract

The invention relates to a static axial compression column assembling machine. The static axial compression column assembling machine comprises a bracket, a slurry tank, a static axial compression column, a pneumatic oil pump, a hydraulic cylinder, and a controller; wherein the hydraulic cylinder is vertically mounted on the bracket; the slurry tank is arranged above the hydraulic cylinder; the static axial compression column is mounted above the slurry tank; a piston element capable of being detached from the piston rod is mounted at the top of the piston rod of the hydraulic cylinder; the slurry tank has an inner chamber into which the piston element can be pushed; the static axial compression column comprises a static column body, wherein the static column body has an inner chamber into which the piston element can be pushed, the piston member is provided with a notch, which comprises a cylindrical part and a conical part, and the conical part penetrates the piston member through a slot. The static axial compression column assembling machine disclosed by the invention has the advantages of guaranteeing a uniform medium and a constant pressure in a column bed of the static column body, guaranteeing preparation and separation effects, also greatly lowering the running cost of the equipment and being applicable to a lab and pilot-scale research and development.

Description

technical field [0001] The invention relates to a static axial compression column packing machine. Background technique [0002] High-performance liquid chromatography preparation technology is a separation technology that can obtain high-purity compounds. Many pharmaceutical researchers hope to have a set of preparation chromatography equipment for the development of production technology and application technology based on chemical analysis. [0003] Like analytical chromatography, the column is the core component of the chromatographic system. The column bed height of modern HPLC preparative chromatographic columns is generally equal to that of conventional analytical columns, generally 250 mm. The main purpose is to reduce the difficulty of scaling up the process from analysis to preparation. At present, the dynamic axial compression column (DAC) is widely used in the preparative chromatography industry. During use, the piston in the chromatographic column relies on the...
