External accumulation of ions for enhanced electrospray ionization fourier transform ion cyclotron resonance mass spectrometry
Abstract
Electrospray ionization (ESI) in combination with Fourier transform ion cyclotron resonance (FTICR) mass spectrometry provides for mass analysis of biological molecules with unrivaled mass accuracy, resolving power and sensitivity. However, ESI FTICR MS performance with on-line separation techniques such as liquid chromatography (LC) and capillary electrophoresis has to date been limited primarily by pulsed gas assisted accumulation and the incompatibility of the associated pump-down time with the frequent ion beam sampling requirement of on-line chromatographic separation. Here we describe numerous analytical advantages that accrue by trapping ions at high pressure in the first rf-only octupole of a dual octupole ion injection system before ion transfer to the ion trap in the center of the magnet for high performance mass analysis at low pressure. The new configuration improves the duty cycle for analysis of continuously generated ions, and is thus ideally suited for on-line chromatographic applications. LC/ESI FTICR MS is demonstrated on a mixture of 500 fmol of each of three peptides. Additional improvements include a fivefold increase in signal-to-noise ratio and resolving power compared to prior methods on our instrument.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
