AI Technical Summary

Technical Problem

Existing DMCC stationary phase tube designs suffer from problems such as mobile phase disturbance, limited density stratification efficiency, and insufficient structural adaptability, resulting in poor separation performance, especially when handling high-viscosity or low-flow-rate fluids.

Method used

The pipe structure design includes a first pipe section, a bend section, and a second pipe section, with an included angle α of 180°>α>0°. The dispersing device is set in the first pipe section, the bend section is used to reduce the flow velocity and provide a stable stratification environment, and the second pipe section is set vertically to achieve solute separation.

Benefits of technology

It effectively reduces eddy currents, improves fluid separation efficiency, and enhances solute separation, especially under high viscosity or low flow rate fluid conditions, thereby improving separation purity and stability.

Abstract

The utility model provides a tube structure for chromatographic separation and a separation device. Wherein the pipe structure comprises a pipe body and a dispersing device, the pipe body comprises a first pipe section, a bending section and a second pipe section which are communicated in sequence, the dispersing device is arranged on the first pipe section, and an included angle alpha of 180 degrees gt is formed between the second pipe section and the first pipe section; alpha gt; 0 DEG. According to the technical scheme, the pipe structure for chromatographic separation comprises the first pipe section, the bending section and the second pipe section, so that a mobile phase can be fully mixed with a stationary phase in the first pipe section through a dispersing device, and then the flowing speed of mixed liquid is adjusted through the bending section, so that the effect that the flowing speed of the mixed liquid is uniform in the second pipe section is ensured. A mobile phase and a stationary phase can be effectively separated, and finally, solute chromatography is realized.
