β¦ Synopsis
A simple, inexpensive home-made timer for coupling cam-controlled samplers to injectors for flow injection analysis is presented. Experimental conditions and a flow diagram are described for the determination of fluoride by means of a fluoride-selective electrode in the concentration range 0.3-10 ppm, with a sample rate up to 120 h-l.

The performance of ion-selective electrodes in a flow injection system under manual or active computer control is discussed\_ The response of the fluoride-selective membrane electrode was not Nemstian, and depended on several parameters. With appropriate standardization, the results were quite satis
