Abstract: In one arrangement, a cartridge includes a cartridge body defining a holding compartment, first and second fractioning compartments, and a number of flow channels formed within the cartridge body. A predetermined quantity of fluid can be held in the holding compartment when the cartridge body is held in a first orientation, and can be poured from the holding compartment to the first fractioning compartment by rotating the cartridge body about a predefined rotation axis to a second orientation, spilling the fluid from the holding compartment to the first fractioning compartment through one of the flow channels. The first fractioning compartment is such that when the cartridge body is in the second orientation, not all of the fluid can be contained in the first fractioning compartment, and fluid that overflows the first fractioning compartment flows through a second flow channel to the second fractioning compartment.

Abstract: A flow-through flow cell (1) for use in HPLC is provided. The inlet (4) of the flow cell (1) is positioned such that flow enters tangentially into the main cavity (2) of the flow cell (1) such that a vortex flow (5) is induced. The cavity (2) has a conical shape with decreasing cross-section in the direction of the outlet (6).Two optical windows (3) and (7) on opposite sides of the flow cell (1) are also provided, for coupling light into and out of the cavity. Fluorescent and absorption detection methods may be used.
