A New Refraction Method for Obtaining Photographic Records of Concentration Gradients

Abstract

WHEN a concentration gradient in a vertical column of solution, for example, an ultracentrifuge cell, is investigated by a refraction method, it is desirable to obtain a diagram relating the refractive index gradient with height in the column of solution. The two data, the height and the corresponding gradient, are in the different methods registered along the same vertical axis or along one vertical and one horizontal axis.
