✦ Synopsis

A double-membrane phase separator for liquid-liquid extraction in flow-injection analysis was designed and its usefulness was examined in order to achieve smooth, long-term and efficient phase separation with good reproducibility. The construction and performance of the flow-injection system using the phase separator were illustrated by the extraction of berberine-perchlorate ion associates.
