ABSTRACT:
A sensing membrane is fixed to one end of a tube comprising polyvinyl chloride. An aqueous sodium chloride solution is contained in the tube, and is in contact with an internal electrode wire. The sensing membrane comprises a support substance of polyvinyl chloride, a sensing substance of quaternary ammonium salt having an alkyl chain having 8 to 16 carbon atoms, and a plasticizer of normal decyl alcohol. Anions in a body fluid sample can be measured with a small measurement error by an electrode provided with the sensing membrane of that composition.
