Abstract

Column for liquid chromatography contains a glass tube for sorbent packing closed with simple column seals and inserted into a jacket made of metal or plastic material. The jacket transfers axial forces exerted on the column seals by liquid pressure action by means of sockets. It secures the tightness of the column, enables the connection of the column to a chromatographic system, and has a protective function at the same time. The columns can be coupled in series by means of doubled sockets.
