Comparison of V-shape Ion Funnel (V-IF) and Two Channel Off-axis Ion Funnel (TCOAIF) in FTICR Mass Spectrometer

摘要

V-IF and TCOAIF can significantly reduce the contamination to the downstream ion guides, the robustness of instrument is enhanced dramatically. An order of magnitude improvement in sensitivity gain for various samples having a wide mass range is obtained by using V-IF and TCOAIF interfaces.
