ABSTRACT:
A flow cell for high performance chromatography, in which the measuring chamber is formed by a bore (12) in a plate (11) and the supply and discharge ducts are formed by bores (13, 14) in the plate (11) communicating with grooves (16, 18) in the plate surfaces (15, 17), the grooves being covered by transparent plates (19, 20) bonded on the plate surfaces, and thus forming closed ducts.
