摘要：

Dynamic response characteristics of an ammonia gas sensing electrode with respect to various membrane modifications were examined. Of particular interest is the effect of a BSA[bovine serum albumin]/glutaraldehyde layer on both forward and return response properties of the electrode. Implications of these variations in response on the measurement of kinetic parameters of enzymes and the construction of enzyme electrodes was also discussed. Responsse fluctuations with respect to variations in membrane thickness were examined.
