Quantitative Infrared Database

CH4 spectrum

The QASoft Database contains quantitative reference spectra of 386 vapor phase compounds. Each compound has a spectrum available in two different resolutions, 0.5, and 1.0 cm-1 . Each spectrum is presented in absorbance units with a known concentration and path length.This permits the computation of gas concentrations from a unknown sample spectrum without the need for calibration gases. (in most cases) The calibration is inherent in the reference spectra. In analyzing for the 386 compounds the only chemical the user will need to handle is his sample.

Data carried in each reference spectrum header include parameters for performing quantitative analysis using QASoft analysis software.

The QASoft Database is available on CD-ROM.
