Device for the analysis of a liquid sample, as well as a method for the determination of an analyte in a dialysate with such a device

摘要

With a device for the analysis of a liquid sample with at least one radiation source, a flexible measuring cell, in which the sample is introduced, at least one radiation detector and an evaluation unit, wherein the samples layer thickness in the flexible measuring cell for carrying out a reference measurement can be varied, a solution is to be provided, by means of which reliable measurements in single-beam arrangement without the need for a reference measurement with a reference solution are possible in a user-friendly.This is achieved in that the coming in contact with the sample. the walls of the measuring cell (4) of interchangeable films (7, 8) are formed. With the proposed measurement technology, taking into consideration the dialysis invention rate again, can be determined by means of markers, in the perfusate used for dialysis, is reliably determined in the analyte concentration bioliquids.
