The most widely used ionization techniques in liquid chromatography–mass spectrometry
(LC–MS) are electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI) …

This review presents the state-of-the-art techniques that couple liquid chromatography (LC)
and mass spectrometry (MS) via atmospheric pressure photoionization (APPI). The different …

This review presents our perspective on the state-of-the-art of atmospheric pressure
photoionization (APPI) for LC/MS. Its focus is on APPI's capabilities and how to utilize them …

The analytical performances of three atmospheric‐pressure sources, electrospray (ESI),
atmospheric‐pressure chemical ionization (APCI), and atmospheric‐pressure …

In response to Gulf of Mexico deepwater horizon oil spill, we have developed an
atmospheric pressure photoionization (APPI) based ultra high performance liquid …

Modern “-omics”(eg, proteomics, glycomics, metabolomics, etc.) analyses rely heavily on
electrospray ionization and tandem mass spectrometry to determine the structural identity of …

Photon activation of ions in the visible and ultraviolet range attracts a growing interest, partly
for its promising applications in tandem mass spectrometry. However, this task is not trivial …

Action spectroscopy of protonated substance P, a model undecapeptide, has been probed
from 5.2 eV to 20 eV. For photon energy above the ionization threshold measured at …

The characterization of membrane proteins is still challenging. The major issue is the high
hydrophobicity of membrane proteins that necessitates the use of detergents for their …
