Indirect ion selective electrode
WebSir, In their review of hyponatraemia, Gill and Leese1 identify pseudohyponatraemia as a methodological problem which can lead to a spuriously low sodium. However, their assertion that this is not a problem when an ion-selective electrode (ISE) is used for sodium analysis needs clarification. Two types of methods using ISEs are currently in use within clinical … Web2 mrt. 2010 · Ion Selective Electrodes (ISEs) are used to measure some of the most critical analytes on clinical laboratory and point-of-care analysers. These analytes which …
