ABSTRACT:
There is described an analytical isntrument for the analysis of fluids such as biological fluids. The instrument includes a fluid dispensing system having a pipette for dispensing fluid test samples and test reagents to assay cartridges. An optical detection system provides a light beam which intercepts a downward travel path of the pipette prior to its reaching the dispense position. Measurement of the intensity of the light beam in conjunction with the position of the pipette enables a controller to indicate the presence or absence of a pipette tip. In addition, interception of the light beam by the pipette initiates a final approach sequence for the pipette to the dispense position above an assay cartridge by a predetermined increment of travel.
