The present invention provides, inter alia, apparatuses and methods for ionizing samples that are in gaseous phase or can be vaporized/sublimated. The samples include samples to be analyzed and mass calibrants that serve as standards. In addition, the present invention also provides calibrant formulations that release mass calibrants in a slow, controlled manner.
