Problems solved by technology

Due to high precision and high stability multi-channel pumps are expensive, which largely leads to high cost of FFE
However, if a general constant flow pump is used, it is difficult for the general constant flow pump to be used for high-precision and high-stability liquid delivery in FFE due to the existence of obvious unstable factors such as pressure pulses.
[0004] Second, the FFE separation mode is single
[0005] Third, FFE is rarely used for sample enrichment
This new MCRB-mediated enrichment model is difficult to complete related research and application in traditional FFE

Abstract

A buffering diverter for the free flow electrophoresis is disclosed, which is composed of a buffer cavity consisting of liquid storage chamber and air cushion chamber for buffering the pressure-flow speed pulses caused by liquid delivering pump, electrolyte / specimen solution inlet tube, air cushion regulating injector the separation chamber for free flow electrophorsis level meter and horizontal level regulating knob. The tens-hundreds stable liquid streams can be generated by its outlet tube.

Description

technical field [0001] The invention relates to a buffer splitting device for free-flow electrophoresis (Free-Flow Electrophoresis, FFE), which is used for electrolyte delivery or sample injection in free-flow electrophoresis. It belongs to the field of biochemical technology. Background technique [0002] Free-flow electrophoresis technology is a high-efficiency preparative separation technology for proteins. It uses a transverse electric field to separate and analyze proteins, viruses and cells in a continuously flowing electrolyte solution. Since the 1970s, FFE has been widely used in the isolation and analysis of genes, drugs, proteins, cells, organelles, and viruses. FFE has many advantages, such as the theoretical recovery rate is close to 100%, and it can be continuously injected for the separation of proteins / cells / viruses, etc. But there are still many problems. [0003] First, FFE is expensive. In FFE, one of the key technologies is the stable delivery of buffe...
