(57) [Summary] [Structure] (i) One or more pH buffers, (ii) 1 One or more pH indicators, and (iii) 1 as a sensitizer One or more surfactants, characterized in that Reagent composition for measuring ionic strength or specific gravity of aqueous liquid sample, And a test piece for measuring ionic strength or specific gravity of an aqueous liquid sample, which is obtained by impregnating, coating or applying the reagent composition. By using the reagent composition of the present invention, Problems when using a conventional reagent composition for measuring ionic strength or specific gravity, that is, there is little change in absorbance, poor reproducibility, little change in color difference in color tone, ionic strength of liquid samples such as urine It is remarkable in that it is difficult to judge with the naked eye when measuring the specific gravity, and that it takes a long time to optically judge a large number of samples due to the slow coloration speed. Produce an effect. |
