Abstract

The importance of chromatogram and spectrum peaks can be measured by mutual information between peak and attribution of measurement behavior. The theory was derived through information entropy. Peak mutual information of gas chromatogram for air pollutant was calculated based upon the theory derived. Mutual information is able to use as a measuring rule to extract important peaks from many trivial peaks and enable peak identification by entropy decomposition into each attribution. As a result a peak which has great mutual information might be useful for chemical interpretation of chromatogram.
