A modular stopped-flow system for use in routine pharmaceutical analysis.

A modular stopped-flow system for routine pharmaceutical analysis is presented. It consists of an inexpensive stopped-flow module which is fitted to a spectrophotometer or spectrofluorimeter and controlled by a simple computer. The automatic technique developed with this system is suitable for the individual and simultaneous determination of various pharmaceuticals (anti-asthmatics, psychotropics, hormones, analgesics, anaesthetics and antiseptics) with satisfactory results.
