Abstract
PURPOSE:To enable an electrode to be used continuously when measuring substances in an organism body, such as blood, by a high polymer electrode film, by removing sticking protein from the electrode efficiently by using an internal standard liquid which contains water, the same substance as the substance to be measured, and protease. CONSTITUTION:When K<+>, Na<+>, Ca<++> and Cl<-> in an organism component such as blood, serum and urine are to be measured, >=5 units/ml alkaline protease produced with bacillary bacteria is contained in an internal standard liquid used for calibration together with a buffer consisting of water, KCl, NaCl and CaCl2 containing the same ions with the substances to be measured, the phosphate of the said metal, tris(hydroxymethyl)aminomethane, and boric acid. Consequently, sticking protein is removed efficiently from a high molecular film electrode used for analysis. Thus, the electrode functions normally for a long period without being contaminated.
