- •
Tyrian purple samples were analysed by UV–Vis spectroscopy and liquid chromatography.
- •
PLS regression was used to correlate spectral and chromatographic data.
- •
Excellent correlation factor and predictive power found for diBr-indigotin content.
- •
Tyrian purple may be non invasively identified through its UV–Vis spectrum.
- •
Hypothesis about mollusc species in archaeological samples was non invasively done.
