This substance is identified in the Colour Index by Colour Index Constitution Number, C.I. 77310.
The tables show the corrected concentrations, corresponding to a
loading of exactly 100 mg/L and the not corrected concentrations
according to the actual loadings (with and without method blank
subtraction if method blanks above LOQ).
