Extensions to peak alignment using reduced set mapping and classification of LC-UV data from peptide mapping
2005 (English)In: Journal of Chemometrics, ISSN 0886-9383, E-ISSN 1099-128X, Vol. 18, no 10, 465-473 p.Article in journal (Refereed) Published
Peak alignment using reduced set mapping (PARS) is extended with a new baseline approximation
and a new dendrogram alignment scheme, which is designed to avoid the issue of selecting a target
chromatogram for the alignment. Two data sets with LC/UV data are studied and it is shown that
peak alignment with PARS increases the class separation substantially in the principal component
score space. The results indicate that it is possible to use PARS for calibration transfer of multivariate
models of chromatographic data.
