Abstract

See full text

Disposition of a wrong liquid for analysis or a liquid for analysis connected to a wrong pipe is detected as abnormal use. A liquid-for-analysis monitor includes: a weighing scale that weighs a container that contains a liquid as a liquid for analysis that needs to be used in analysis; a density storing part that stores a density ρ of the liquid for analysis; and a liquid-for-analysis determining part configured to obtain a variation ΔM between a weight of the container weighed by the weighing scale before a decreasing operation that decreases the liquid for analysis and a weight of the container weighed by the weighing scale after the decreasing operation, and determine whether the liquid for analysis has been normally used in the decreasing operation or not, based on the obtained variation ΔM, a volume V of the decrease in the liquid in the container in the decreasing operation, and the density ρ of the liquid for analysis stored in the density storing part.
