ABSTRACT:
Quality control of an analyzing system that includes a portable analyzer with insertable single-use cartridges whose sample chamber contains optical and/or electrochemical sensors is accomplished by bringing the sensors in the single-use cartridge into contact, or are in contact with, a calibrating and/or conditioning medium, the calibrating and/or conditioning medium exhibiting chemical and/or physical parameters which influence the characteristic of at least one of the sensors. Just before a sample is measured, the sensors are contacted with a quality control liquid which is identical with the calibrating and/or conditioning medium within a predetermined desired range of accuracy for the sample components to be measured, as regards the chemical and/or physical parameters influencing the characteristic of at least one sensor during calibration and/or conditioning. The instantaneous control values obtained on the basis of the calibration values are subsequently compared to known target control values.
