Abstract:
(EN) A measurement cell 1 includes: a droplet guide section 3 provided to one inner wall surface of an interior space 15 and having a plurality of wells; and a trap section 2 provided to another inner wall surface and having a recessed section for capturing floating droplets. The present invention comprises: a step for pouring a fluid containing a plurality of droplets and an oil into the measurement cell 1, in a state where the trap section is positioned up and the droplet guide section is down, thereby trapping the plurality of droplets in the trap section; and a step for inverting the measurement cell and causing the plurality of droplets trapped in the trap section to be captured by the plurality of wells of the droplet guide section. The present invention makes it possible to trap droplets floating in oil at a high capture rate.
(FR) Une cellule de mesure 1 comprend : une section de guidage de gouttelettes 3 disposée sur une surface de paroi interne d'un espace intérieur 15 et ayant une pluralité de puits; et une section de piégeage 2 disposée sur une autre surface de paroi interne et ayant une section évidée pour capturer des gouttelettes flottantes. La présente invention comprend : une étape consistant à verser un fluide contenant une pluralité de gouttelettes et une huile dans la cellule de mesure 1, dans un état dans lequel la section de piègeage est remontée et la section de guidage degouttelettes est abaissée, ce qui permet de piéger la pluralité de gouttelettes dans la section de piégeage; et une étape consistant à inverser la cellule de mesure et à amener la pluralité de gouttelettes piégées dans la section de piégeage à être capturées par la pluralité de puits de la section de guidage de gouttelettes. La présente invention permet de piéger des gouttelettes flottantes dans de l'huile à un taux de capture élevé.
(JA) 内部空間15の一方の内壁面に複数のウエルを有する液滴ガイド部3が設けられ、他方の内壁面に浮遊する液滴を捕捉する窪み部を有するトラップ部2が設けられた測定セル1内に、トラップ部を上に液滴ガイド部を下にした状態で複数の液滴とオイルとを含む流体を流し、トラップ部に複数の液滴をトラップする工程と、測定セルを反転させ、トラップ部にトラップされた複数の液滴を液滴ガイド部の複数のウエルに捕捉させる工程と、を有し、オイルに浮遊した液滴を高捕捉率でトラップする。
