Abstract[English]
Calibrant compositions comprising a plurality of synthetic peptides for calibration of a mass spectrometer in either positive or negative mode are provided. The synthetic peptide calibrants exhibit desirable ionization characteristics, solubility, and solution stability, and are easily washed out of the system such that no interfering signals are left behind. Methods for calibration of mass spectrometer in positive or negative ion mode using a single calibrant composition are also provided.[French]
L'invention concerne des compositions d'étalonnage comprenant une pluralité de peptides synthétiques pour l'étalonnage d'un spectromètre de masse dans un mode positif ou négatif. Les étalons peptidiques synthétiques présentent des caractéristiques d'ionisation souhaitables, une solubilité et une stabilité de solution, et sont facilement éliminés du système de telle sorte qu'il ne reste aucun signal brouilleur. L'invention concerne également des procédés d'étalonnage de spectromètre de masse dans un mode d'ions positifs ou négatifs à l'aide d'une composition d'étalonnage unique.
