In this paper,the pCO_2 sensitive electrode was studied for continuous measurement.The solid electrolyte membrane and gas-permeable membrane were coated on the surface of the pH sensitive electrode which was fabricated based on the SnO_2/ITO glass substrate.According to the experimental results,the pCO_2 sensitive electrode shows the sensitivity of about 35 mV/decade in detection range between 0.1 mmol/L and 50 mmol/L.Moreover,the investigated sensing structure exhibits the convenient and pragmatic properties of the pCO_2 measurement.In summary,the advantages of the pCO_2 sensitive electrode are low-cost and disposable based on the separative structure.
