Abstract[English]
The disclosure provides compositions, methods, and kits that find use in calibrating a mass spectrometer, and can include one or more predetermined concentration(s) of one or more calibrant molecule(s) that comprise a polyethylene glycol (PEG) compounds that have a single functional group that can be ionized by an ion source, and a solvent for dissolving the calibrant molecule(s). The calibrant molecule(s) and compositions including them can be used in either positive or negative ionization mode, and can be used for calibrating a variety of mass spectrometers (e.g., APCI, ESI) operating in a variety of acquisition modes (e.g., MRM, MS/MS, etc.).[French]
L'invention concerne des compositions, des procédés et des kits qui trouvent une utilisation dans l'étalonnage d'un spectromètre de masse et qui peuvent comprendre une ou plusieurs concentrations prédéterminées d'une ou de plusieurs molécules d'étalonnage qui comprennent un composé de polyéthylèneglycol (PEG) qui a un seul groupe fonctionnel qui peut être ionisé par une source d'ions et un solvant pour la dissolution de ladite ou desdites molécules d'étalonnage. Ladite ou lesdites molécules d'étalonnage et les compositions les comprenant peuvent être utilisées en mode d'ionisation soit positif soit négatif et peuvent être utilisées pour l'étalonnage de divers spectromètres de masse (par exemple, APCI, ESI) fonctionnant en divers modes d'acquisition (par exemple, MRM, MS/MS, etc.).
