متن کاملFourier transform ion cyclotron resonance detection: principles and experimental configurations
Fourier transform ion cyclotron resonance mass spectrometry is based on image current detection of coherently excited ion cyclotron motion. The detected signal magnitude and peak shape may be understood from idealized behavior: single ion, zero-pressure, spatially uniform magnetic field, three-dimensional axial quadrupolar electrostatic trapping potential, and spatially uniform resonant alterna...
متن کاملFourier transform ion cyclotron resonance mass spectrometry: a primer.
This review offers an introduction to the principles and generic applications of FT-ICR mass spectrometry, directed to readers with no prior experience with the technique. We are able to explain the fundamental FT-ICR phenomena from a simplified theoretical treatment of ion behavior in idealized magnetic and electric fields. The effects of trapping voltage, trap size and shape, and other nonide...
متن کاملProbing trapped ion energies via ion-molecule reaction kinetics: Fourier transform ion cyclotron resonance mass spectrometry.
The kinetic energy-dependent Ar(+)+ N2 ion-molecule reaction has been used as a chemical "thermometer" to determine the kinetic energy of ions produced by electron ionization and trapped by using a Fourier transform ion cyclotron resonance (FTICR) mass spectrometer. The rate constant for this reaction obtained on the FTICR mass spectrometer was compared to previous work, which allowed a kinetic...
متن کاملDesign and performance of an atmospheric pressure ion mobility Fourier transform ion cyclotron resonance mass spectrometer.
This manuscript presents our initial results and development of a novel hybrid instrument that combines atmospheric pressure ion mobility spectrometry (AP-IMS) with Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS). Our preliminary results obtained from atmospheric pressure mobility separation of peptide mixtures combined with high-resolution FTICR mass analysis are demonst...
