Document Type and Number:
WIPO Patent Application WO/2023/216591
Kind Code:
A1
Abstract:
A purification separation column for clinical detection pretreatment, a pretreatment apparatus, a pretreatment method, and an application. The purification separation column comprises a column tube (1) open at at least one end, the column tube (1) having disposed therein a filtering assembly, and a filtrate to be filtered entering through the opening from the outside of the column tube (1), passing through the filtering assembly and then entering an inner cavity of the column tube (1); the filtering assembly comprises, sequentially arranged from bottom to top, a first sieve plate (6), a water blocking layer (4), a filler layer (3) and a second sieve plate (2). The purification separation column is primarily used for carrying out pretreatment on a clinically detected sample to be detected; conventional solid-phase extraction requires undergoing a plurality of operations such as activation, adsorption, washing and elution, wherein the involved solution reagents differ from one another; the present purification separation column achieves one-step pretreatment of a sample to be detected.
