Abstract

A method for determining the quality of a hose in an automated analyser system, comprising the steps of collecting data of a wash curve by measuring the light intensity through a hose with an optical sensor during washing of a hose; determining and recording the voltage changes related to changing light intensities; extracting an aspiration time and time for completing of a an aspiration process from said data; determining changes in the data of the most recent wash curves. The disclosure further relates to a device for preforming said method.
