Document Type and Number:
WIPO Patent Application WO/2023/135888
Kind Code:
A1
Abstract:
The present invention involves: dissolving a dye in a volatile liquid to prepare a dye-containing volatile liquid that contains the dye at a predetermined concentration (step 11); suctioning the dye-containing volatile liquid by a dispenser and discharging the same into a measurement vessel (step 12); drying the dye-containing volatile liquid discharged into the measurement vessel (step 13); adding, after the drying, a predetermined amount of a low-volatile liquid having a volatility lower than that of the volatile liquid to the measurement vessel to dissolve the dye and prepare an assessment liquid (step 14); conducting an optical measurement on the assessment liquid (step 15); and determining a discharged amount that is the volume of the dye-containing volatile liquid discharged into the measurement vessel, on the basis of a measured value of the assessment liquid obtained by the optical measurement, the added amount of the low-volatile liquid, and the concentration of the dye in the dye-containing volatile liquid (step 16). As a result, the amount of a volatile liquid dispensed by a dispenser such as a micropipette can be accurately measured.
