Abstract

A dispensing apparatus includes a syringe which has a piston and sucks and discharges a liquid; and a storage unit which stores therein a reference driving profile indicating a reference of a driving position and a driving time at starting the piston. The apparatus also includes a position detector which detects an actual driving position of the piston; a timer which measures an actual driving time of the piston; and a driving controller which controls driving of the piston based on the reference driving profile, the driving controller creating an actual driving profile based on the actual driving position and the actual driving time of the piston, and the driving controller comparing the reference driving profile with the actual driving profile to determine based on a result of the comparing whether the dispensing is proper or not.
