Determination Of The Anthocyanin Concentration

13.24: Mass Spectrometry

anthocyanin Many natural pigments have conjugated systems 22 Chromophore: light absorbing portion of a molecule Beer’s Law: There is a linear relationship between absorbance and concentration !A = ε c l A = absorbance c = concentration (M, mol/L) l = sample path length (cm) ε = molar absorptivity (extinction coefficient)
