Abstract
Method and device for determining in dialysis treatment the content of waste products in the outgoing dialysis liquid from the dialyzer. Measurement of the concentration of a certain substance or a combination of substances included in the waste products is effected spectrophotometrically directly on the outgoing dialysis liquid from the dialyzer. For that purpose there is provided after the dialyzer in or after the dialysing machine a measuring cell for spectrophotometric measurement. The measurement value obtained is multiplied by the flow of dialysis liquid for determining the content of said substance or said combination of substances in the outgoing dialysis liquid from the dialyzer.
