Mass Spec Calibration Compounds and Spectra

Calibration Compounds are used by the mass spectrometer user to adjust the mass spec calibration scale as well as the relative intensities of mass spec peaks from low to high mass. This is particularily necessary for the setup of quadrapole mass spectrometers. The most popular calibration compound is FC-43, also known as Perfluorotributylamine. Other calibration compounds are used to adjust the high resolution mass spectrometer calibration scale. The following pages list the data available on the most common calibration compounds in various mass spec techniques including low resolution, high resolution, Electron Impact, Chemical Ionization and Negative Ion Mass Spectrometry. Where available, the suppliers of these calibration compounds are listed.
