METHOD FOR PRODUCING A FLUIDIC CONNECTION COMPONENT FOR CHROMATOGRAPHY

摘要

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.

1. A method for producing a fluidic connection component for chromatography, the fluidic connection component comprising a main body and at least one insert held in the main body, wherein the main body is prefabricated with at least one aperture for the at least one insert, the method comprising:
connecting the at least one insert to the main body securely and fluidically tightly by a thermal process that thermally expands the main body or the insert that only occurs during the thermal process, and after completion of the thermal process, retaining a thermally induced change in volume of the main body or of the insert to cause a radial clamping force between the main body and the insert to occur in a clamping region along a course of the aperture to form a secure and fluidically tight connection between the main body and the insert at temperatures within a working temperature range.
