Abstract:
1. Device for automatically analysing a liquid sample, this device comprising: a series of bowls for a single use, mobile along a reeling off axis and each comprising a bottom, an upper face opposite the bottom having an opening and two opposing shoulders extending from front and back sides of the bowl approximately in the plane of the opening, the bowls being engaged side by side and joined to each other by a flexible film secured to said shoulders and covering at least partially the openings of said bowls, said flexible film having a series of oblong orifices having spaced apart edges and extending respectively above the openings of said bowls and transversing to said reeling off axis, wherein said spaced apart edges allow insertion of injection and/or sampling means with no contact with edges of the orifice, said device further comprising an optical detection station through which pass said film and said bowls, said station comprising a light source generating a light beam which illuminates the upper face of each bowl present in the station, and an opto-electronic detector placed below said bottom, said film being made of a light diffusing material for rendering the light beam more homogeneous, wherein said light source of said detection station is an infrared light source and said opto-electronic detector comprises a load transfer detector bar.
