WITec has released TrueMatch, a software component for accessing and creating Raman spectral databases. It can search existing libraries of Raman spectra to identify sample components and also allows users to create their own catalog of acquired spectra to assist in their research. TrueMatch is available as an integrated option with the WITec Project FIVE software environment, and databases can be brought directly into use in post-processing. Multi-spectral searches enable the user to identify several spectra simultaneously, and return hit rates that show the probability of a match for each individual spectrum. This greatly accelerates the process of characterisation and complements WITec’s standard data analysis features. Demix search uses databases to describe acquired spectra in terms of pure substances, which can then be physically located in an image. Seeing the distribution of pure chemical components matched to sample features gives the researcher a precise visualisation. Generated reports can be stored for further use in subsequent measurements, amplifying the effectiveness of the system as a whole. In addition to the proprietary WITec Raman database capability included with TrueMatch, compatible versions of ST Japan’s range of databases are available.
