Dye Analysis by Chromatography

The purpose of the Dye Analysis database is to collect data from LC/DAD/MS analyses of actual samples from artifacts and standard dye materials. Each record represents one sample. The record includes information on the sample source, interpretation of the results, the sample preparation procedure, and details of the analytical technique. Images of the chromatograms are included, both DAD signals (at one or more different wavelengths of absorption) and MS (possibly including total ion chromatograms, base peak chromatograms, or extracted ion chromatograms). A table of specific compounds identified in the sample includes common name of the compound, retention time during the analysis, molecular weight (or major ion, if a fragment), and major UV/visible absorbance wavelengths. Finally, images of spectra are included. These include UV/visible absorption spectra of individual compounds and mass spectra. In general, mass spectra that only show the molecular ion will not be included. Spectra that contain collision-induced fragments in addition to the molecular ion, or MS/MS spectra, if acquired, will be included when possible. Many analyses often include small, unidentified peaks. These generally will not be discussed in the analysis record, but users should consult the original data source for full discussion.

How to use the Dye Analysis database

The full list of dye records are listed below. Shorter lists can be found by clicking on the links above for the subsections within Dye Analysis. Additionally, individual compounds may be searched for using the box in the upper right and the list of results will indicate all samples in which the compound was found.
