High-resolution ion cyclotron mobility spectrometry.
A novel ion mobility spectrometry instrument incorporating a cyclotron geometry drift tube is presented. The drift tube consists of eight regions, four curved drift tubes and four ion funnels. Packets of ions are propagated around the drift tube by changing the drift field at a frequency that is resonant with the ion's drift time through each region. The approach trims each packet of ions as it...
متن کاملElectrospray ionization high-resolution ion mobility spectrometry-mass spectrometry.
A hybrid atmospheric pressure ion mobility spectrometer is described which exhibits resolving power approaching the diffusion limit for singly and multiply charged ions (over 200 for the most favorable case). Using an electrospray ionization source and a downstream quadrupole mass spectrometer with electron multiplier as detector, this ESI-IMS-MS instrument demonstrates the potential of IMS for...
متن کاملA scanning frequency mode for ion cyclotron mobility spectrometry.
A new operational mode for an ion cyclotron mobility spectrometry instrument is explored as a possible means of performing high-resolution separations. The approach is based on oscillating fields that are applied to segmented regions of a circular drift tube. Ions with mobilities that are resonant with the frequency of field application are transmitted while nonresonant species are eliminated. ...
متن کاملHigh-resolution ion mobility measurements
Gas phase ion mobility measurements can resolve structural isomers for polyatomic ions and provide information about their geometries. A new experimental apparatus for performing high-resolution ion mobility measurements is described. The apparatus consists of a pulsed laser vaporization/desorption source coupled through an ion gate to a 63-cm-long drift tube. The ion gate is a critical compone...
متن کاملUltra High-Mass Resolution Paper Spray by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
Paper Spray Ionization is an atmospheric pressure ionization technique that utilizes an offline electro-osmotic flow to generate ions off a paper medium. This technique can be performed on a Bruker SolariX Fourier transform ion cyclotron resonance mass spectrometer by modifying the existing nanospray source. High-resolution paper spray spectra were obtained for both organic and biological sampl...
