Abstract
In two‐dimensional Fourier transform ion cyclotron resonance mass spectrometry (2D FTICR‐MS), scintillation noise, caused mostly by fluctuations in the number of ions in the ICR cell, is the leading cause for errors in spectrum interpretation. In this study, we adapted an algorithm based on singular value decomposition and first introduced by Cadzow et al. ( IEE Proceedings Pt. F 1987, 134, 69) to 2D FTICR‐MS and we measured its performance in terms of noise reduction without losing signal information in the 2D mass spectrum. Copyright © 2011 John Wiley & Sons, Ltd.
