Abstract
Means for determining whether or not a reagent necessary for a chemical reaction is normally discharged is provided for a liquid dispensing device that dispenses the reagent for the reaction. A liquid dispensing device as such means includes a temperature controller that controls a temperature of a reaction position to any appropriate temperature and a temperature monitor part that monitors the temperature of the reaction position, monitors with the temperature monitor part a change in the temperature of the reaction position when the dispensing device discharges a reagent, and when a temperature change amount deviates from a beforehand determined threshold range, determines abnormal dispensation.
