Abstract
La présente invention concerne un procédé de séparation d'ions ayant le même rapport de masse/charge mais des caractéristiques de mobilité d'ions différentes, basé sur les principes de focalisation d'ions de la spectrométrie de mobilité ionique à forme d'onde asymétrique à haute résolution. Les isomères comprenant des anions moléculaires en phase gazeuse des acides aminés leucines et isoleucines sont séparables par le procédé de la présente invention. Le procédé de la présente invention permet également l'identification de différents conformères d'ions dans le même état de charge, notamment des conformères présents dans certains états de charge de la protéine ubiquitine bovine.
