Take the guesswork out of your spectral analysis with the Thermo Scientific™ Sigma Proteins and Peptides FT-IR Spectral Library, a material-specific subset of the larger Sigma Biochemical Condensed Phase Library. Our comprehensive libraries feature fully-reviewed, high-quality spectroscopy databases, to enabling confident compound identification for a variety of environmental, forensic, pharmaceutical and industrial applications as well as create greater efficiencies in your lab.
Spectra acquired by Sigma-Aldrich Co.™ and examined and processed at Thermo Fisher Scientific. The spectra include compound name, molecular formula, CAS (Chemical Abstract Service) registry number and Sigma catalog number.
Contains 747 spectra
Data format: Deresolved
About Spectral Libraries 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. Thermo Scientific libraries span applications for Hazmat, Forensics, Food, Polymers and Organic Chemistry.
