Ion Scattering Spectrometry

Ion Balance Mass Spectrometry

We have developed a technique to simultaneously compare the cyclotron frequencies of two single ions to obtain atomic mass ratios with fractional accuracies at or below 10−11. Much like a balance scale, this two-ion technique cancels many sources of noise and error – chief among them magnetic field noise. The new mass comparisons are used in combination with γ-ray wavelength measurements, perfo...

Ion Mobility Mass Spectrometry

for more complex analysers for automated sample processing and plant control. The separation time will continue to decrease; in the past there has been limited interest in fast separations but this could change as automated sample processing is developed. Increasing use of coupled techniques such as GC-GC, liquid chromatography-GC, and supercritical Suid chromatography-GC for the separation of ...

Ion Mobility-Mass Spectrometry

Development of atmospheric pressure ionization ion mobility spectrometry and ion mobility spectrometry mass spectrometry

Quadrupole ion trap mass spectrometry.

A number of other features of ITMS systems that will enhance their ability to analyze biological macromolecules are worth mentioning. As has already been demonstrated for ESI/quadrupole, ESI/magnetic sector, and ESI/FTICR systems, the capability of inducing fragmentation of the ESI-generated multiply charged ions of biological macromolecules in the capillary/skimmer region of the ESI source and...
