Abstract: A dispensing device includes a dispenser (4) operable to dispense a calibration liquid sample (5) having a calibration particle (8) into a container (3) containing liquid (2) during a calibration operation and to dispense a liquid sample (5) into the container (3) during a subsequent dispensing operation, and a detection device (6) configured to scan a partial volume region (7) of the container (3) to determine an upper limit (9) and a lower limit (10) of the partial volume region (7) in the calibration operation by determining a height of the calibration particle (8) above a container bottom (12), and by determining the upper limit (9) and the lower limit (10) of the partial volume region (7) based on the determined height of the calibration particle (8). The detection device (6) is further configured to scan the partial volume region (7) to detect one or more particles (8) located in the liquid sample (5) in the dispensing operation.

Abstract: The invention relates to a method for detecting a particle in a container filled with liquid, the method having the following steps: dispensing a liquid sample into the container, scanning a partial volume area of the container in order to detect a particle located in the liquid sample, characterized in that an upper limit and a lower limit of the partial volume area is determined in a calibration operation upstream of the dispensing process.
