Examinations were made on the effect of swelling characteristics of a gel on the different property between lower and higher G-number gets. Measurement was made on the volume of the gel matrix (V_g) of Sephadex G-10 to G-200 and Bio-Gel P-2 to P-100 to find the isotherm from adsorption of some dyes from aqueous solution. The V_g value of Sephadex G-10 was about 16 times greater than that of G-200. G-series of Sephadex and P-series of Bio-Gel were divided into two groups from the markedly different V_g values between lower and higher G- or P-number gels. Adsorption isotherm of food dyes was divided into three classes according to the shape of the initial slope of the curve; (1) S-2 curve for food red 3 on Sephadex G-10,(2) L-2 curve for food violet 1 on Sephadex G-10,and (3) constant partition curve for food blue 1 on Sephadex G-10,and for food violet 1,food red 3,and food blue 1 on Sephadex G-200.
