We report a new hybrid mass spectrometer, which is a combination of a quadrupole ion trap and an orthogonal time‐of‐flight (TOF) mass spectrometer. This new configuration consists of a collisional‐damping chamber (CDC) inserted between an MS n ‐capable ion trap and a high‐mass‐accuracy orthogonal‐TOF mass spectrometer. Because the CDC converted an ion packet into an energy‐focused and quasi‐continuous beam, a high mass resolution of over 10 000 and a high mass accuracy of better than 3 ppm were achieved. Moreover, the ratio of the maximum detectable m/z to the minimum detectable m/z , which is referred to here as the mass window, was improved to more than 10. Copyright © 2004 John Wiley & Sons, Ltd.
