AN OPTICAL ROTATION STOPPED FLOW APPARATUS

Fumiyuki Watanabe, Toshihiko Nagamura

Open publisher page 0 citations

Abstract

Abstract A stopped flow apparatus has been proposed for optical rotation changes. This apparatus, even when the signals of optical rotation changes are masked by absorption changes, can detect only the signals of optical rotation changes. The apparatus is examined by several model reactions: The maximum sensitivity is 0.01 degree of rotation, the dead time ca. 80 msec. The 50% change of transmittance does not affect the signals of optical rotation changes.
