What protein charging (and supercharging) reveal about the mechanism of electrospray ionization.
J. Am. Soc. Mass Spectrom. 25(10) , 1675-93, (2014) Understanding the charging mechanism of electrospray ionization is central to overcoming shortcomings such as ion suppression or limited dynamic range, and explaining phenomena such as supercharging. Towards that end, we explore what accumulated observations ... |

Matrix-assisted ionization vacuum for high-resolution Fourier transform ion cyclotron resonance mass spectrometers.
Anal. Chem. 86(14) , 6792-6, (2014) Matrix-assisted ionization vacuum (MAIV) produces charge states similar to electrospray ionization (ESI) from the solid state without requiring high voltage or added heat. MAIV differs from matrix-assisted laser desorption/ionization (MALDI) in that no laser ... |
