Abstract
AbstractAn 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 sensing surfaces, including gas‐sensing, liquid polymer membrane and solid‐state based ISEs. Commercial ISEs employed for the evaluation of the flow‐through cell were ammonia, calcium and iodide ion‐selective electrodes. The observed electrode slopes were −58.8 ± 0.9, 25.2 ± 0.5 and −58.3 ± 0.9, mV change / activity decade, respectively, over a wide log‐linear range using a 100 μL sample volume in the FIP mode. Sample throughput rates as fast as 240 injections/h and analytically useful peak height responses can be achieved using injected sample volumes as low as 25 μL with all three types of ISEs.
