Abstract[English]
A method for annotating product ions of a spectrum is disclosed. A product ion mass spectrum is received. A parameter that indicates the mass spectrum was produced using a radical-induced dissociation method is received. At least one charge state mass-to-charge ratio (m/z) adjustment based on the parameter is performed for at least one product ion peak of the mass spectrum and the adjustment is compared to one or more other product ion peaks of the mass spectrum. The at least one product ion peak is annotated based on the comparison. The charge state adjustment includes the loss of an electron or the loss or gain of a hydrogen atom. The radical-induced dissociation method includes electron-based dissociation (ExD), ultraviolet photodissociation (UVPD), or infrared photodissociation (IRMPD).[French]
L'invention concerne un procédé d'annotation d'ions produits d'un spectre. Un spectre de masse d'ions produits est reçu. Un paramètre indiquant que le spectre de masse a été produit à l'aide d'un procédé de dissociation induite par radicaux est reçu. Au moins un ajustement du rapport masse/charge (m/z) de l'état de charge basé sur le paramètre est effectué pour au moins un pic d'ion produit du spectre de masse et l'ajustement est comparé à un ou plusieurs autres pics d'ion produit du spectre de masse. Le ou les pics d'ions produits sont annotés sur la base de la comparaison. L'ajustement d'état de charge comprend la perte d'un électron ou la perte ou le gain d'un atome d'hydrogène. Le procédé de dissociation induite par radicaux comprend une dissociation à base d'électrons (ExD), une photodissociation par ultraviolets (UVPD) ou une photodissociation infrarouge (IRMPD).
