    • Differential ion mobility separations in the low-pressure regime 

      Shvartsburg, Alexandre A.; Haris, Anisha; Andrzejewski, Roch; Entwistle, Andrew; Giles, Roger (American Chemical Society, 2018-01-02)
      Ion mobility spectrometry (IMS) in conjunction with mass spectrometry (MS) has emerged as a powerful platform for biological and environmental analyses. An inherent advantage of differential or field asymmetric waveform ...

    • Ion mobility spectrometry of macromolecules with dipole alignment switchable by varying the gas pressure 

      Shvartsburg, Alexandre A.; Andrzejewski, Roch; Entwistle, Andrew; Giles, Roger (American Chemical Society, 2019-06-05)
      Since inception in the 1980s, differential or field asymmetric waveform ion mobility spectrometry (FAIMS) was implemented at or near the ambient gas pressure (AP). Recently, we developed FAIMS at 15-30 Torr within a mass ...

    • Ion mobility spectrometry of superheated macromolecules at electric fields up to 500 Td 

      Andrzejewski, Roch; Entwistle, Andrew; Giles, Roger; Shvartsburg, Alexandre A. (American Chemical Society, 2021-08-23)
      Since its inception in 1980s, differential or field asymmetric waveform ion mobility spectrometry (FAIMS) has been implemented at or near ambient gas pressure. We recently developed FAIMS at 15–30 Torr with mass spectrometry ...
