Abstract
메타놀, N,N-디메칠포름아미드 및 아세토니트릴 속에서 유리전극의 pH 응답성을 여러가지 pH의 완충용액으로 시험한 바 전극을 물속에 보관하는 것보다 측정하고저 하는 용매속에 보관하는 것이 더 빨리 전위가 안정되었다. 같은 용매에서 용액의 염기성에 비례하여 응답속도가 느리고 강염기성 용액에서는 안정한 전위를 얻기 어려웠다. 산성용액에서의 pH 응답성은 보다 빠르나 같은 용액의 pH 측정에서도 전극의 사용한이력에 따라 응답성과 측정치에 차이가 생겼다.

The responsive characteristics of hydrogen-responsive glass electrode in various buffer solutions of methanol, N,N-dimethylformamide and acetonitrile were examined. The potentials were attained more rapidly with an electrode stored in the same solvent medium than that stored in water before use. However, the time to be required for a stable potential increased with the basicity of buffer solution, and it was not provide a constant potential in the strong basic solution of these solvent. Even in acidic solution, the potential was varied according to the past usage of the electrode.
