Reusable Liquid Chromatographic Columns

US Patent:
7704388, Apr 27, 2010
Filed:
Jan 31, 2006
Appl. No.:
11/307312
Inventors:
Yawu Chi - Sharon MA, US
Lixin Cao - Princeton NJ, US
Ying Xu - Edison NJ, US
Assignee:
Luknova, Inc - Princeton NJ
International Classification:

US Classification:

Abstract:
A reusable liquid chromatographic column consists of three parts, a column body with an integral outlet port molded on one end, a sealing insert with an inlet port, and a perforated cap providing downward force to compress the sealing insert into the column body. A wedge-like seal is employed to seal the connection between the sealing insert and the column body. Two filters on both ends of the column body are used to prevent escape of packing materials from the column chamber under pressure. Hand tightening is adequate to seal the connection by screwing the perforated cap onto the column body. The column is reusable due to its simple disassembling and reassembling processes. It is also disposable due to its inexpensive fabricating materials and manufacturing process.
