More Information
Summary:The disclosure relates to a method for determining the quality of a hose in a peristaltic pump of an automated analyser system, comprising the steps of collecting data of an aspiration process through the hose by measuring the light intensity through the hose during aspiration with an optical sensor; determining and recording the voltage changes related to changing light intensities measured by the optical sensor; extracting an aspiration time and determining whether the aspiration process was completed from two sets of data of voltage changes relating to the aspiration time and whether the aspiration process was completed; determining changes in the two sets of data of voltage changes for the aspiration time and the determination whether the process was completed. The disclosure further relates to a use of said method.
