SPECTROSCOPIC PH MEASUREMENT USING OPTIMIZED MIXTURES OF REAGENTS TO EXTEND MEASUREMENT RANGE |
摘要 |
An indicator mixture that allows pH measurement over a broader range of pH or to a higher accuracy than available using conventional spectroscopic techniques. In particular, the mixture of the present invention is comprised of two or more reagents such that when combined, the reagent mixture is capable of either detecting: (1) a pH range broader or more accurate than that the reagents individually, or (2) pH more accurately than the reagents individually. Also disclosed are methods of making and using the mixture.
