The method was internally and externally validated for a log Po/wrange between-1.54 and4.75, with higheraccuraciesthan conventional liquid chromatographic methods.9 p.application/pdfengcc-by (c) Subirats i Vila, Xavier et al., 2018http://creativecommons.org/licenses/by/3.0/esElectroforesi capil·larCromatografia de líquidsLipofíliaCapillary electrophoresisLiquid chromatographyLipophilicityinfo:eu-repo/semantics/article6807652018-06-19info:eu-repo/semantics/openAccess
