We report a direct comparison of the mass measurement accuracies (MMAs) obtained on different mass spectrometry instrument types; a magnetic sector as the ‘gold standard’ and an electrospray ionization time‐of‐flight (ESI‐TOF) instrument. Sixty samples, obtained from the Department of Chemistry at North Carolina State University, were analyzed on each instrument. Data are presented and compared between the different instruments. The average absolute MMAs achieved for the magnetic sector and Agilent ESI‐TOF mass spectrometers were 3.0 and 1.1 ppm, respectively. Copyright © 2008 John Wiley & Sons, Ltd.
