Complementary Identification of Protein Digests using a Combined MALDI and ESI Dual Source Q-Tof Mass Spectrometer (ABRF 2002)
--The limit of detection was determined for MS data acquired on
a Q-Tof mass spectrometer in both electrospray ionisation (ESI) and
matrix assisted laser desporption ionisation (MALDI). --The dynamic
range of both ESI and MALDI ionisation modes were investigated with
unseparated mixtures of typtic peptides. --The resulting MS/MS spectra
from low energy CID fragmentation are compared and contrasted for both
MALDI and ESI.
