The present article reviews the mass spectrometric fragmentation processes and
fragmentation energetics of leucine enkephalin, a commonly used peptide, which has been …

Abstract The Mars Organic Molecule Analyzer (MOMA), a dual-source, ion trap-based
instrument capable of both pyrolysis-gas chromatography mass spectrometry (pyr/GC–MS) …

The collision energy or collision voltage necessary to obtain 50% fragmentation
(characteristic collision energy/voltage, CCE or CCV) has been systematically determined …

Elucidating the structures and stabilities of proteins and their complexes is paramount to
understanding their biological functions in cellular processes. Native mass spectrometry …

We describe the construction and characterisation of a nano-oscillator formed by a Paul trap.
The frequency and temperature stability of the nano-oscillator was measured over several …

Miniature ion trap mass spectrometry with the unique ability of tandem-in-time analysis is
extensively used in public security and environmental pollution detection. In this study, a …

Detecting megadalton matrix-assisted laser desorption/ionization (MALDI) ions in an ion trap
mass spectrometer is a technical challenge. In this study, megadalton protein and polymer …

In recent years, it has become increasingly interesting to understand the performance of
mass spectrometers at pressures much higher than those employed with conventional …

Rationale There are many chemical measurement scenarios that would benefit from hand
portable mass spectrometry tools including forensics, environmental monitoring, and safety …

A two-dimensional tandem mass spectrometry (2D MS/MS) scan has been developed for the
linear quadrupole ion trap. Precursor ions are mass-selectively excited using a nonlinear ac …
