Self-Calibrated Ion-Selective Electrodes [PDF]

open access: yes, 2023
Ion-selective electrode (ISE) potentiometry is reliable only if on-site calibration using a standard solution is performed before the ion measurement. The complex device and operation required for calibration hinder the implementation of ISEs in decen ...
