Abstract
An assembly allowing the quick and easy connection or replacement of a column in a LC system. The assembly includes a cooperating male twist lock member and a female twist lock member. When rotated relative to one another, the male member and female member are removably attached. When attached, the assembly provides a leak-free seal at one end of a guard column, with the other end of the guard column attached to a LC system through tubing which is secured to a holder in which the guard column is positioned. In the preferred embodiment of the invention, the assembly is biocompatible and presents only chemically inert surfaces to the flow of the mobile phase and sample.
