PURPOSE:To eliminate adverse effect due to the attaching of a protein or the like, by drying a coated film of a volatile solvent solution under a condition with an inertial force imparted on the surface of response surface thereof to make an ion responsive film. CONSTITUTION:In the making of an ion responsive film, the solvent is evaporated from a coated film of a solution under a condition with an inertial force imparted in the direction of the responsive surface thereof. This produces an ion responsive film very smooth in the surface as compared with those made by mere coating and drying and thus, eliminates adverse effect from interference with the potential response and deterioration otherwise caused by adsorption of proteins coexisting in a sample. |
