Home Mass Spectrometry Cluster-ToF High Mass Resolution

High Mass Resolution

This spectrum shows the world record for mass resolution of time-of-flight mass
spectrometers. These are C60 molecules ionized with a laser radiation at 198nm.
The insert shows the first peak, mass 720 amu, recorded at a mass resolution
better than 40000 (FWHM).



This spectrum with enlargements shows CsO cluster at 100000amu with a mass
resolution of 22000 (FWHM).



This spectrum taken with the ALBATROS Esi-ToF shows a Cs salt of tridecafluoroheptanoic acid,
demonstrating the high resolution of the ALBATROS :
