The Thermo Scientific™ Sigma™ Biochem Condensed Phase FT-IR Spectral Library is a spectral collection of the most common chemicals in the Sigma Biochemicals and Reagents catalog. The spectra represent a wide range of chemical classes of interest to labs doing biochemical research or QC.
Our comprehensive libraries feature fully-reviewed, high-quality spectroscopy databases, enabling confident compound identification for a variety of environmental, forensic, pharmaceutical and industrial applications.
Spectral library searching has long been an extraordinarily valuable tool in the analytical chemist's toolbox. Our extensive series of spectral libraries includes information specific to application, industry or spectral technique.
Spectral library searching based on digital matching of spectral signatures is a very effective way of performing qualitative identification of compounds. Because FT-IR and Raman spectroscopic signatures are based on molecular functional groups, even if the exact compound is not present in the libraries, the list of matching compounds from a spectral library search can often lead to identification, or at least classification, of the material.
