摘要：
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.).
