摘要： There are provided a method of detecting dispensed quantity in which without the need of detecting a surface of liquid accommodated in a container, a liquid quantity can be detected only by measuring pressure change; and a relevant liquid suction monitoring dispensing apparatus. There is provided a method of detecting dispensed quantity for detection of the quantity of liquid suctioned and discharged by a dispensing apparatus including a pipette tip, a liquid suctioning/discharging mechanism for the pipette tip, a pressure sensor capable of detecting the pressure within the pipette tip, and a lifting and lowering mechanism for the pipette tip, which method comprises: an insertion step for inserting a distal end of the pipette tip down to the deepest zone of a container accommodating liquid to be measured; a suction pressure measuring step for without moving of the pipette tip, while suctioning the liquid into the pipette tip at a predetermined suctioning rate, measuring any pressure change during the suctioning; and a suction detecting step for on the basis of pressure change measured, determining the state of suction. Further, there is provided a liquid suction monitoring dispensing apparatus capable of practicing this method.
