Abstract
A mixing device for liquid chromatography for the radial mixing of at least two fluids comprises a tubular mixing line, and a helical flow-guiding element arranged in the mixing line. One or more spacing elements located within an interior region of the mixing line are adapted to maintain a predetermined distance between the outer sides of the helical flow-guiding element and an inner wall of the mixing line. A mixing unit according to the present invention may include such a radial mixing device, with a longitudinal mixing device being connected downstream from this radial mixing device.
