## Abstract Cluster ions from fast atom bombardment of liquid alcohols and nitriles were examined using a continuousβflow technique. Protonated molecular M~__n__~H^+^ species are the dominant cluster ions observed in molecules of formula M. The abundances of the M~__n__~H^+^ cluster ions decrease m
We propose to use cluster ions that are much larger than the molecular ions as primary ions for organic secondary ion mass spectrometry. Incident Ar cluster ion beams with energies from 10 to 20 keV and a mean size of about 1000 atoms/cluster were used. Secondary ions were measured for a thin argini
