"A review is made of methods of determination of dyes in different media. Due to the widely varying chemical nature of dyes, there is no single method which would suffice for their chromatographic separation from each other and from natural co-extractives. The best current methods involve high performance liquid chromatography with a diode array spectrophotmetric detector. This method naturally requires a library of dye spectra. Twenty-two dyestuffs which are commonly used in the Eastern Townships of Quebec are identified, and their ultraviolet-visible spectra are determined"--Abstract, page 2.
