NUMERICAL APPROACH TO THE EXPLANATION OF THE RESPONSE-TIME OF THE SEVERINGHAUS TYPE ELECTRODE

The response and reproducibility of the Severinghaus type electrode we re examined by numerical methods. The diffusive behaviour of the gaseo us component present in the bulk internal electrolyte solution affects the entire electrode system. That is, this solution makes it difficul t for the electrode to reach an equilibrium state. It was found that w ith improving the state of the bulk internal solution, a steady state could be achieved in a short period.
