|Title:||Multivariate Curve Resolution Applied To Ms/ms Data Obtained From Isomeric Mixtures|
|Abstract:||Multivariate curve resolution (MCR) was applied to MS/MS data for modeling isomeric mixtures. A pentaquadrupole mass spectrometer consisting of three mass analyzing and two reaction quadrupoles was used to obtain a second-order data from mixtures of 2-, 3- and 4-ethylpyridine. MCR allowed recovering of the mass spectral profiles of the three isomers as well as the concentration distribution profiles. The results indicate that MCR is a suitable tool for MS/MS data analyses to distinguish and quantify the positional isomers in mixtures. © 2001 Elsevier Science B.V. All rights reserved.|
