Abstract
A clinical analyzer has been described that includes a probe to aspirate a fluid. The probe is washed between aspirations to reduce carryover. The wash operation includes both an internal and an external wash, where the internal wash operation is terminated prior to terminating the external wash. In one example, the probe wash can be implemented on an integrated clinical chemistry/immunoassay analyzer.
Claims6
A method comprising:
- determining a sampling volume of a test sample aspirated by a probe of an analyzer;

- and
- flushing an exterior surface of the probe with the wash fluid for Y seconds, the flushing of the interior region and the exterior surface occurring at least partially simultaneously, wherein the flushing of the exterior surface is to terminate after the flushing of the interior region is to terminate, and wherein Y is based on the sampling volume.
