OPUS/SEARCH

The search of spectral libraries is a powerful tool and represents the typical approach to identify spectra of unknown materials.

With the release of the OPUS 7.5 software the SEARCH package was completely revised including a new attractive design and strongly improved usability. New functions such as a powerful mixture analysis and the automated subtraction of a library spectrum for residual spectrum search enhance the identification power especially for multi-component spectra.

In addition to the simple and powerful info search inside spectral libraries an automated internet search of selected library info provides a comfortable way to get the most out of the identification result. As the findings of an analysis typically have to be documented in a report all search results can be exported into a clearly arranged analysis report.

Features:

• Spectrum Search: comparison of query spectrum and library spectra using Bruker’s unique peak based standard algorithm or classical point-to-point correlation.
• Residual Search: automated subtraction of a library spectrum for identification of additional bands in the sample spectrum. 

• Mixture Analysis: identifies and quantifies single components in mixture spectra. A composite spectrum from the library component spectra and the difference spectrum between composite and query spectrum (=residual) visualizes the quality of the match.
• Peak Search: search of user defined peak tables including intuitive set-up of peak tables by interactive peak pick on one or several reference spectra.
• Internet Search: online search for any info term of a library spectrum.
• Information Search: powerful and intuitive search of terms and numbers in the complete information matrix of one or several spectral libraries. Includes option for advanced info search for accurate discovery of specific information.
• Setup and Editing of User Spectra Libraries: the user is guided through an intuitive setup procedure. Contains the option to import info tables from external programs by copy & paste.
• Structure Search: option to search chemical structures (requires OPUS/STRUCTURE package)
• Extensive Selection of spectral Libraries: libraries available from Bruker, ST Japan, Sadtler and FDM.
