ISE Electrodes

Measurements using an ion selective electrode (ISE) are applicable in virtually every laboratory. ISE's can be used to measure ion concentrations in water, food, pharmaceuticals and biological samples. Ion selective electrodes can be used as endpoint indicators or to perform direct measurement and incremental techniques.
