Solution density measurement method, the sample cell and the solution density measuring device which are used for this

摘要

Churning operation losing, it streamlines the measurement of density of the specific component of the suffering inspection liquid to a greater extent by obtaining the mixed liquid of the suffering inspection liquid and the reagent liquid. While agitating by filling the reagent liquid to the suffering inspection liquid, while the mixed liquid which includes with the aforementioned suffering inspection liquid and the aforementioned reagent liquid profit, next, irradiating light to the aforementioned suffering inspection liquid, before at least filling the aforementioned reagent liquid, it measures with the 1st optical quality of the aforementioned suffering inspection liquid, and after filling the aforementioned reagent liquid, the 2nd optical quality of the aforementioned suffering inspection liquid from the aforementioned 1st optical quality and the aforementioned 2nd optical quality measures the specific component density in the aforementioned suffering inspection liquid.
