Ion cloud manipulation using the radiofrequency-only-mode as an improvement for high mass detection in fourier transform mass spectrometry.


It has been difficult to achieve the expected high resolving power for high-mass biomolecule ions in Fourier transform mass spectrometry. Our hypothesis is that ion clouds produced by laser desorption or injection are diffuse and produce poor signals. To test the hypothesis, clouds of benzene molecular ions produced by electron ionization were purposefully… (More)
