Ion mobility–mass spectrometry

Journal of Mass Spectrometry, 2008
AbstractThis review article compares and contrasts various types of ion mobility–mass spectrometers available today and describes their advantages for application to a wide range of analytes. Ion mobility spectrometry (IMS), when coupled with mass spectrometry, offers value‐added data not possible from mass spectra alone. Separation of isomers, isobars,

Inverse Ion Mobility Spectrometry

Analytical Chemistry, 2009
A novel method is proposed for enhancing the separation power of ion mobility spectrometry (IMS) and other similar pulsed techniques, such as time-of-flight mass spectrometry. In this technique, rather than generating an ion packet, a dip is created in the ion beam. This is achieved by an inverse pulse applied to the shutter grid.

Correlation ion mobility spectrometry

The Analyst, 2017
Using a linearly swept chirp function to modulate a Bradbury–Nielsen (BN) ion gate and application of a common signal processing technique (cross-correlation), we outline a method for obtaining high resolution IMS–MS spectra with ion gate duty cycles approaching 50%.

Hadamard Transform Ion Mobility Spectrometry

Analytical Chemistry, 2006
A detection scheme that makes use of the Hadamard transform has been employed with an atmospheric-pressure ion mobility spectrometer fitted with an electrospray ionization source. The Hadamard transform was implemented through the use of a linear-feedback shift register to produce a pseudorandom sequence of 1023 points.
