Abstract

An apparatus for the continuous determination of low molecular weight components of a flowing fluid for example a body fluid comprises dialysis means (3) having a semi-permeable membrane for permitting a test fluid flowing on one side of the membrane to diffuse therethrough into a carrier fluid flowing on the other side of the membrane, an analytical test arrangement (19) connected into the outflow path of the carrier fluid, valve means (37,38 Figure 2 not shown) for control of the test fluid and pump means (8) for pumping the fluids, the test arrangement (19), the valve means (37,38), and the pump means (8) being mounted in a basic framework (32), and the dialysis means (3) being so arranged that its output for the carrier fluid is connected to a connection piece on the basic framework (32) connected to the analytical test arrangement (19). <IMAGE>
