摘要
A chromatography column comprises a pipe that contains a tubular metal casing with an inlay and sealing ring. The inlay is configured as a plastics material tube and is pushed or drawn into the metal casing and a sealing ring of plastics material is connected to the inlay at the end. Because of this structure, a connection to further system parts is possible, which is carry-over-free, inert on the inside, liquid-tight, optionally gas-tight, and pressure-tight. A connection element and connection connect the pipe to feed and/or discharge lines of a capillary system. Pipes, connection elements and connections of this type are advantageously used in low and high pressure systems, such as, for example, in an HPLC column. The use of such systems is advantageous in in-vitro diagnostics and in liquid handling applications.
