ABSTRACT:
A method for determining the concentration of an ion, atom or molecule bound in a complex. A reliable determination of the concentration of the ion, atom or molecule to be determined is possible in accordance with the invention in that the complexing of the ion, atom or molecule is prevented at least during the determination of the concentration by the addition or withdrawal of a substance. Also contemplated is a dialyser having a haemo-dialyser and/or a haemo-filter and an extra-corporal blood circulation with which a device for the adding of citrate to the blood is connected upstream and a device for the adding of a substitution solution containing ions to the blood is connected downstream of the haemo-dialyser and/or of the haemo-filter. Ion concentration in the dialysate downstream of the haemo-dialyser and/or of the haemo-filter is detected with respect to the direction of flow of the dialysate.
