Spectral database index

This page lists in alphabetical order all existing entries within the database, followed in the other columns by other record identifiers such as sample ID, material class, chemical information, and spectral data. From this list, users can click on the links associated with each spectral data to get the information for each reference material. Users can toggle between the existing data entries by clicking on the data type buttons - XRF, FTIR, or Raman Spectrum. An interactive spectra viewer that allows users to visualize and analyze the spectra of each sample is available on each individual record file page.
