Spectral Library Search

The infrared spectrum of a molecule is like a fingerprint. By comparing the spectrum of an unknown compound to a library of data, the spectroscopist can identify the unknown. This technique has wide applications in many fields such as forensics, environmental chemistry, research, industrial quality control, and teaching.

FTIR Spectrum of xylene with best match from the EPA Vapor Phase Library

Essential FTIR does not include spectral libraries, but Essential FTIR can search libraries of spectra available from third-party vendors. All of these vendors offer high-quality collections of Transmission FTIR, ATR, Vapor Phase and Raman spectra at attractive prices.

Build and Search your own libraries using Essential FTIR.

Most spectral library formats are proprietary. A library builder program places your spectra into a database with an undocumented format. If the software that built the libraries is no longer available, your data is trapped in the database with no way to view it or extract it. If you no longer have the original spectral datafiles, your data is lost.

This can't happen with Essential FTIR, because user libraries are simply folders containing spectral data files. To maintain the library, you just drop files into the folder.

Bring your data with you when you use Essential FTIR.

In addition to being able to read your FTIR datafiles, Essential FTIR can search user libraries that have been generatedin these formats:

• Winfirst from Mattson Instruments
• Grams Spectral ID user libraries
• Perkin Elmer user libraries
• Thermo Omnic user libraries
• Sadtler user libraries
