Abstract: Native electrospray ionization-mass spectrometry (ESI-MS) is inherently susceptible to nonvolatile salts in solution, due to ion formation resulting from the so-called "charged-residue mechanism" (CRM). The presence of nonvolatile salts leads to peak broadening and shifting… read more here.

Abstract: The common method of mass analysis in a linear ion trap mass spectrometer is to eject ions with different mass-to-charge ratios (m/z) at different times by resonance excitation. Ions are ejected onto an electron multiplier… read more here.
