CALIBRATION COMES FROM THE QUANTITATIVE REFERENCE SPECTRA
Calibration is inherent in the reference spectra. A person who uses QASoft does not need to handle any gas mixtures or other calibration chemicals. The only chemical he works with is the sample he is analyzing. The one reference spectrum for each compound will apply to all concentrations, as long as the rules for use of QASoft are adhered to. See the topics CONCENTRATION RANGE FOR QUANTITATIVE ANALYSIS, QUANTITATIVE ACCURACY OF THE SPECTRA, and RULES FOR QUANTITATIVE ANALYSIS OF GASES.
