Abstract
The present disclosure describes a differential-type carbon dioxide sensor, which includes a pH-electrode, a bicarbonate electrode, and a chloride electrode, and a reference electrode, which is enclosed in a chamber. The pH electrode has a pH-sensitive membrane and the bicarbonate electrode has a bicarbonate-sensitive membrane, which comprises 30% by weight of a polymer matrix, 30% by weight of a carbonate or bicarbonate ion-selective material, 30% by weight of a plasticizer, and 10% by weight of a lipophilic additive based on total weight of the bicarbonate-sensitive membrane. Further, the chloride electrode has a membrane with no selectivity towards bicarbonate and towards salicylate, which is within a predetermined therapeutic range having a concentration of salicylate less than 1.5 mmol/L. The pH electrode, the bicarbonate electrode, and the chloride electrode operate in tandem with each other.
