Abstract
A method and apparatus for determining solute levels by affinity viscosimetry involving a sensitive fluid, in which the sensitive fluid flows continuously through a first hydraulic resistor in the flow direction of the dialysis chamber, and the sensitive fluid modified by dialysis simultaneously flows through another resistor, wherein the pressure differences between the resistors is determined on-line with the aid of pressure sensors and converted into a relative value which is approximately proportional to the concentration of solute.
