FTIR-ATR spectra of reference standards used for calibration—genuine (pure) beeswax, and adulterants (paraffin— Paraffinum solidum , stearic acid— Acidum stearicum ).
FTIR-ATR spectra of reference standards (paraffin-beeswax mixtures containing different proportions of paraffin) used for calibration.
