Device for capillary chromatography and method for manufacturing such a device

A device for capillary chromatography comprising:

• at least one receiving space arranged in a circuit board and of a form such that the receiving space is suitable for at least partially receiving a coiled part of a tubular capillary separation column;
• wherein the at least one receiving space is an annular receiving space that is defined by an upper wall, a lower wall, and a peripheral wall, and the coiled part of the capillary separation column is at least partially received in the annular receiving space in a substantially dose-fitting manner against each said wall of the receiving space;
• wherein the annular receiving space surrounds an open center in the circuit board to enable coiling of the capillary separation column into the annular receiving space from the open center;
• and
• wherein heating elements are arranged on both a top side and a bottom side of the circuit board for heating the capillary separation column in a uniform manner.
