✦ Synopsis
A fast-response flow cell Hrlth ion-selectwe electrodes was constructed for contmuous-flow measurements m au-segmented streams without debubblmg The flow system was optmuzed for fluonde and chlonde detennmatlons With a flow-rate of 4 ml mm-' a samphng rate of 480 h-' was achieved for chlonde determmations, the average relative standard deflation m all mstances was better than 2%

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
## Abstract A battery powered portable monitor based on flow injection potentiometry has been developed weighing 1.8 kg, constructed in a carry‐case and applicable for remote site monitoring. Portability has been achieved using a light weight rechargeable Ni‐Cd battery‐pack (7.2 V). The flow inject
Continuous flow analysis (CFA) is suitable for rapid and reliable determination of free Fe III in organic-free, UV-oxidized seawater when used in conjunction with an extrapolation method that predicts the steady-state potentials of an Fe III chalcogenide glass ion-selective electrode (ISE) by using
