Iso-octyl Phosphorite as a Calibration Material in FDMS
-
-
Abstract
The field desorption mass spectrum (FDMS) of iso-octyl phosphorite displays intense cluster ion peaks of nM+1~+. These ion peaks distribute between m/z 150 and 1500 with rational interval. So iso-octyl phosphorite can be used as calibration reference in field desorption mass spectrometry.
