Abstract

A method for producing a fluidic connection component for chromatography is described. A connection component includes a main body and at least one insert held in the main body. The main body is prefabricated with an aperture for the at least one insert. The at least one insert is connected to the main body securely and fluidically tightly by a thermal process and by making use of a thermal expansion of the main body and/or of the insert that occurs during the thermal process. The method may include a thermally induced change in volume of the main body and/or of the insert that is retained after completion of the thermal process. The material and the geometry of the main body and of the insert and the thermal process are chosen such that, after completion of the thermal treatment, there is a secure and fluidically tight connection.
