  • Differential carbon dioxide sensor
    Patent number: 10317359
    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.
    Type: Grant

  • Acetate detecting sensor
    Patent number: 6689272
    Abstract: An electrochemical sensor for detecting the presence and amount of acetate in cell culture and fermentation media. The electrochemical sensor has a pH electrode, an internal reference electrode, a special high-tensile strength gas permeable membrane, and internal reference electrolyte such that acetate concentration can be measured using a pretreatment buffer having a pH of about 5.5.
