A processing method for separation column and through-hole of large-capacity high-speed countercurrent chromatograph

Abstract

The invention discloses a processing method for a separation column and a through hole of a large-capacity high-speed countercurrent chromatograph, which comprises a tube main body. The shaft is flexibly connected; one side of the main body of the tube is provided with a feed pipe connector and a discharge pipe connector, and a coiled column tube is wound on it, and the two ends of the coiled column tube are respectively connected with the feed tube connector and the discharge tube The connecting parts of the inlet and outlet pipes are also connected with the inlet and outlet pipes respectively. The inlet and outlet pipes pass through the fixing parts, the threading holes, the central through pipe and the central shaft in turn, and the fixing parts are used to fix the inlet and outlet. The position of the material pipe, the threading hole is composed of a straight hole and an inclined hole, and the central through pipe is processed with a first hole and a second hole for the passage of the inlet and outlet pipes respectively. The first hole and the second hole are symmetrically arranged and aligned with the center. The surface of the through pipe is 30-40 degrees, and the feed pipe, the column pipe and the discharge pipe are connected in sequence. Realize the reliable unwinding of the inlet and outlet pipes of the separation column under high-speed rotation.

Description

technical field [0001] The invention relates to the technical field of high-speed countercurrent chromatography, in particular to a processing method for a separation column and a through hole of a large-capacity high-speed countercurrent chromatography. Background technique [0002] High speed countercurrent chromatography (HSCCC for short) is a continuous and efficient liquid-liquid partition chromatography separation technology developed in the 120s of the 20th century, which does not require any solid carrier or support. In recent years, natural, green, and safe have become the latest health concepts that people pursue, so this new separation and purification technology has attracted more and more attention. At present, HSCCC is widely used in biomedicine, biochemistry, food, natural products, environmental analysis, etc. Many fields have become an important pillar of my country's modern science and technology and economic construction. [0003] HSCCC has great advantage...
