A continuous flow cell for use with the Bendix-NPL automatic polarimeter. Application to neomycin analysis

Abstract

The design of a micro-cell (110-µl capacity) for use with the Bendix-NPL polarimeter is described. The cell has been used for the continuous flow analysis of neomycin and other aminoglycoside antibiotics using an ion-exchange column of small dimensions. Eluted material with an optical rotation down to 0·006° can be measured.
