We report the first coupling of a desorption electrospray ionization (DESI) ion source to Fourier transform ion cyclotron resonance mass spectrometry (ESI‐FT‐ICR‐MS) for high‐resolution protein analysis. The DESI FT‐ICR‐MS source design is described in detail along with preliminary data obtained on peptides and proteins ranging from 1 to 5.7 kDa. Copyright © 2006 John Wiley & Sons, Ltd.
