Embodiment Construction

[0024] Such as Figure 1 to Figure 5 as shown,

[0025] The internal energy storage constant pressure preparation column device includes a support, a preparation column and a hydraulic oil cylinder.

[0026] The support includes a horizontal base 11, an upper support plate 12 and a lower support plate 13, the upper and lower support plates are connected by three columns 16, the upper support plate is circular, and the hydraulic cylinder 2 is installed at the center of the upper support plate 12, in a vertical position. A U-shaped notch 14 is provided at the center of the lower support plate 13, and the U-shaped notch is located at a certain distance below the hydraulic cylinder, which is less than the working range of the hydraulic cylinder, and is used for fixing the preparation column 3. The lower support plate 13 and the base 11 are connected by several C-shaped rods 15, and the C-shaped rods protrude backward, so that a relatively large operating space can be obtained. ...

Abstract

The invention relates to an inner storage constant-pressure preparative column device, and provides a miniaturization device. The device comprises a bracket, a preparative column and a hydraulic cylinder. The hydraulic cylinder is vertically mounted on the bracket, and a U notch for fixing the preparative column is arranged at a distance under the hydraulic cylinder; and the hydraulic cylinder acts on the preparative column and drives the preparative column to compress. The preparative column has functions of automatic inner column pressure compensation and automatic column bed defect repair, and also can ensure constant pressure state of packing in the column. The device is especially suitable for development and research on different target products and different processes in a laboratory, so as to greatly reduce development costs, and improve development efficiency.

Description

technical field [0001] The invention relates to the technical field of high performance liquid phase preparative chromatography, in particular to a novel internal energy storage constant pressure preparative column device. 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 20-25cm), the main purpose is to reduce the difficulty of process amplification from analysis to preparation. At present, the dynamic axial compression column (DAC) ...
