Title: ANNULAR CHROMATOGRAPH COMPRISING A FRACTION DETECTOR
Abstract:
The invention relates to a device and a method for detecting the escape of liquid from a particle bed (1) or a base plate (2) of a continuous annular chromatograph (20). In a preferred embodiment, detectors (27) are arranged in a detector plate (40) which is located downstream of a collecting ring (3) and is offset in relation to the latter. Each detector, together with a quartz tube forms a measuring cell. The measuring cells are connected to the outlets of the collecting ring via tube connections. In order to prevent the formation of bubbles, the eluate drain lines emanating from the collecting ring form a type of siphon.
