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 pp

## Abstract A procedure was developed for determination of salt in various meat products using a chloride ionβselective electrode. The technique of batch injection analysis was used together with an ultrasound based sample extraction step. Various kinds of meat products were analyzed. The relative
An improved wall-jet configuration type flow-through cell has been developed for use with commercial ion-selective electrodes (ISEs) and has been evaluated in the flow injection potentiometric (FIP) mode. The flow-through cell was designed to accommodate commercial ISEs that employ a range of sensin
