    • High-resolution differential ion mobility separations/orbitrap mass spectrometry without buffer gas limitations 

      Baird, Matthew A.; Shliaha, Pavel V.; Anderson, Gordon A.; Moskovets, Eugene; Laiko, Victor; Makarov, Alexander A.; Jensen, Ole N.; Shvartsburg, Alexandre A. (American Chemical Society, 2019-04-29)
      Strong orthogonality between differential ion mobility spectrometry (FAIMS) and mass spectrometry (MS) makes their hybrid a powerful approach to separate isomers and isobars. Harnessing that power depends on high resolution ...

    • Linear and differential ion mobility separations of middle-down proteoforms 

      Garabedian, Alyssa; Baird, Matthew A.; Porter, Jacob; Fouque, Kevin Jeanne Dit; Shliaha, Pavel V.; Jensen, Ole N.; Williams, Todd D.; Fernandez-Lima, Francisco; Shvartsburg, Alexandre A. (American Chemical Society, 2018)
      Comprehensive characterization of proteomes comprising the same proteins with distinct post-translational modifications (PTMs) is a staggering challenge. Many such proteoforms are isomers (localization variants) that require ...
