| Abstract |
Method POLY-W109.01 procedures utilize a spectrophotometer to measure the absorbance of light as it passes through a sample that has been prepared by reaction with TanniVer 3® Folin phenol reagent. Concentrations of all hydroxylated compounds (polyphenols) that give a proportional blue color are determined by comparison of the absorbance of the sample to the absorbance of tannic acid solutions of known concentrations. |
