For the miniature mass spectrometer (MS) with a continuous atmospheric pressure interface
(CAPI), the gas in the multi-stage chambers directly affects the performance of the …

We explore the kinetic processes that sustain equilibrium in a microscopic, finite system.
This is accomplished by monitoring the spontaneous, time-dependent frequency evolution …

Mass spectrometry (MS) using an electron multiplier for intact protein analysis remains
limited. Because of the massive size and complex structure of proteins, the slow flight speed …

We propose a method to investigate the vibrational dynamics of single polyatomic molecular
ions confined in a Paul trap. Quantum logic techniques are employed to detect the recoil of …

For portable, remotely operated systems in space and defense, relaxed vacuum
requirements are a strong advantage of ion trap mass analyzers. However, ion traps are …

For decades, experimentalists and theoreticians have used gas-phase water-ion clusters to
probe solute-solvent interactions at a molecular level. Vibrational spectroscopy on these …

Ion trap mass spectrometers present a powerful analytical tool which not only enables mass
spectrometric determination of analyte species but also has the added feature of being able …
