Abstract: An internal liquid for a reference electrode containing lithium chloride (LiCl) and ammonium nitrate (NH.sub.4 NO.sub.3) in a dissolved state at a ratio [NH.sub.4 NO.sub.3 ]/[LiCl].gtoreq. 4. Internal liquid also contains AgCl to saturation for use with an Ag--AgCl internal electrode, and is in a gellated state or impregnated in a highly water-absorbent synthetic resin. It is used in conjunction with a comparison electrode or an internal reference electrode for an ion-selective electrode.Drying up of the internal liquid in the gellated state is minimized so that the function of the internal liquid as a liquid bridge may be displayed for a prolonged period of time. If the ionic concentration of the liquid under examination is changed, liquid potential difference remains substantially unchanged to provide a stable reference electrical potential.

Abstract: A concentration measuring method and an apparatus measures the concentration of an objective solvent in a mixed solution by flowing a mixed solution through a tube, transmitting light through the mixed solution as it flows through the tubing and measuring the quantity of light transmitted through the fluid. The concentration of the objective solvent in the mixed solution is measured on the basis of either the quantity of light transmitted, the diameter of a light beam received, or a point of convergence of the light transmitted through the mixed solution. These factors being dependent on the concentration of the objective solvent in the mixed solution.
