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.

Abstract: The invention relates to a flow cell for absorption detection, in which a tube through which flow is to pass is held at its opposite ends in a supporting flange in each case and is suspended in a substantially cantilevered manner, the two supporting flanges being connected rigidly to each other in order to avoid stresses accidentally introduced into the tube.

Abstract: The invention relates to a positioning means for a flow cell used for optical detection, comprising a base having at least one contact face, the contact face being provided to make contact with the end of the flow cell, wherein the base has at least one reference face, which is to be aligned and/or positioned relative to the flow channel of a flow cell, and wherein the base is designed to receive a connecting piece in such a way that the latter assumes a predefined attitude and alignment relative to the flow channel.
