Evaluation of detection limit and selectivity coefficient for single ion-selective sensors and an array of non-selective sensors

摘要

A method of estimation of detection limit and selectivity of sensor array has been suggested. Proposed method allows to compare sensor parameters in solutions evaluated for separate sensors (ion-selective electrodes) and multisensor systems. Iihas been found that detection limit of non-selective sensor array is an order of magnitude lower and that selectivity is 5 times higher in comparison with corresponding parameters of single selective sensors.
