Abstract

The present invention provides a system for analyzing a sample liquid comprising a test tape having a plurality of test elements, a tape transport device which successively transports the test elements to a sample application site while advancing the tape, and a measuring device which scans the test elements loaded with sample liquid at a measuring site. The measuring site is located at a distance from the sample application site in the direction of tape movement. The tape transport is interrupted in order to exactly position a wetted area of the test elements carrying a sample liquid at the measuring site by means of a positioning device that responds to the presence of sample liquid on the test element.
