Verfahren zur Qualitätskontrolle eines portablen Analysensystems

摘要

For the quality control of an analysis system, a portable analyser has a disposable cassette with optical and/or electro-chemical sensors in the sample zone. The sensors in the cassette are brought into contact with a calibration and/or conditioning medium. The medium has chemical and/or physical parameters which affect the characteristics of at least one sensor. Directly before measurement of a sample, the sensors are placed in contact with a quality control fluid which matches the effect on the sensor(s) by the sample within the required measurement accuracy. The actual control value is compared with known nominal control values. Also claimed is a control fluid which matches the chemical or physical parameters which affect the sensor(s) during calibration or conditioning within the required measurement accuracy for the sample to be measured.
