Abstract

PURPOSE:To defoam in an extremely short time, to continuously defoam and to surely defoam even a small amt. of liq. by providing a reduced-pressure chamber above a defoaming chamber furnished with the inlet and the outlet of liq. through a gas permeable membrane. CONSTITUTION:A defoaming chamber 2 is formed at a part of a liq. passage and a reduced-pressure chamber 3 is provided along the upper part of the liq. passage through a gas permeable membrane 4. An inlet 10 and an outlet 11 are connected to the defoaming chamber 2 and a discharge port 12 is protruded from the reduced-pressure chamber 3. When the defoamer thus constituted is incorporated in the passage of the eluate 14 sent by a feed pump 15, the air bubbles 16 mixed into the eluate 14 or generated are floated in the defoaming chamber 2, passed through the gas permeable membrane 4, sucked by the reduced-pressure chamber 3 and discharged from the discharge port 12 to the outside of the system. The eluate 14 contg. no air bubbles is continuously sent into a column 17 in this way.
