✦ Synopsis

A simple and versatile pneumatically-operated two-layer rotary valve is described for simultaneous introduction of samples and diversion of analytical streams in flow injection analysis. Examples of applications include valve configurations with time-controlled sample volume and with loop-controlled sample volumes in one or two loops; both configurations are useful in routine analyses of samples of highly varying analyte concentrations. The usefulness of the valve for ion-exchange preconcentration procedures is also demonstrated.
