Abstract
A composition, method, and kit for calibrating a mass spectrometer including a predetermined concentration of a calibrant having a mixture of amino acid polyethylene glycol compounds and a solvent for dissolving the calibrant. The calibrant can be used in either positive or negative ionization mode, and it can be used in calibrating an atmospheric pressure chemical ionization or an electrospray mass spectrometer. The calibrant can include a mixture to enable calibration across a broad range of masses.
