Abstract:Based on the diode-array UV detector,a rapid and intuitive method for identification of the purity of the chromatographic peak was established by removing noise,normalization,calculating the Euclidean distance and clustering analysis.This method not only can be used to intuitively judge the purity of the peak,but also can be used to judge the location of the interferential peak.It provides important information for evaluating chromatographic peaks and the further studies.
Keywords:Purity of Chromatograph Peak  Diode-Array Detector  Clustering Analysis  Spectrum
