It is frequently said that DESI-MS follows a similar ionization mechanism as ESI because of
similarities usually observed in their respective mass spectra. However, practical use of …

The effects of liquid and gas phase additives (chemical modifiers) on the ion signal
distribution for Substance P (SP), recorded with a nanoelectrospray setup, are evaluated …

Flavonoids are polyphenolic secondary metabolites with extensive biological activities and
pharmacological effects. Exploring the interactions of flavonoids with proteins may be helpful …

Gas phase modification in ESI-MS can significantly alter the charge state distribution of small
peptides and proteins. The preceding paper presented a systematic experimental study on …

Exposure of electrospray droplets to organic vapors was shown to dramatically reduce alkali-
metal adduction on protein ions and shift protein charge states. Since DESI-MS is affected …

The results of a comparative study of the stabilizing effects of amino acids and imidazole on
electrospray ionization mass spectrometry (ESI–MS) measurements of protein-ligand …

Up-front CID fragmentation is a phenomenon where molecular ions are activated and
fragment as they enter the atmosphere-to-vacuum region of the mass spectrometer, and …

This work consists of two parts that are concerned with different aspects of the ion dynamics
in quadrupole ion trap (QIT) mass spectrometers. The first part describes the development …

The growing need for fast separations, improved signal sensitivity and selectivity, in the
analysis of intact proteins and non-covalent complexes in the gas-phase has driven the …

Electrospray ionization mass spectrometry (ESI-MS) is a soft ionization technique that allows
detection of macromolecules, such as intact proteins, by the formation of multiply charged …
