Abstract

PURPOSE: To expand the available solution range of an optical saturation temperature meter by attaching and fixing microcrystal of solute on the transparent surface of the bottom of a sample container in the shape of a film.
CONSTITUTION: On the transparent surface of the bottom 7 the microcrystal S of solute is attached and fixed in the shape of an extreme thin layer and thereabove a sample container 1 with poured-in solute is placed on a sample placing stage to be projected with the ray of light from a light source 3, then the transmitted light reaches the light receiving element 4 to be transduced into the electromotive power. Next, when the heating unit 5 is conducted, the solution is gradually heated, namely at the time when the saturation temperature is just exceeded the scattering of light in the sample liquid A reduces to suddenly increase the quantity of light reaching the light receiving element 4. From the temperature corresponding to the point of inflexion of said electromotive force the saturation temperature of said sample can be measured. Thereby the high purity solution, which has been difficult to measure or even the solution in the state of highly over-saturation can be treated.
