Angular Averaged Profiling of the Radial Electric Field in Compensated FTICR Cells

Year: 2012

Type: article

Abstract: A recent publication from this laboratory reported a theoretical analysis comparing approaches for creating harmonic ICR cells. We considered two examples of static segmented cells--namely, a seven segment cell developed in this laboratory and one described by Rempel et al., along with a recently described dynamically harmonized cell by Boldin and Nikolaev. This conceptual design for a dynamically harmonized cell has now been reduced to practice and first experimental results obtained with this cell were recently reported in this journal; this publication reported details of cell construction and described its performance in a 7 tesla Fourier transform mass spectrometer. We describe the extension of theoretical analysis creating harmonic ICR cells to include angular-averaged radial electric field calculations and a discussion of the influence of trapping plates.
