Abstract
It has been demonstrated that the mass resolution of the quadrupole io n trap, or Paul trap, when operated as a mass spectrometer, may be var ied over a wide range by reducing the mass scanning rate. Mass resolut ions of 3.1 x 10(7) and 1.2 x 10(7) have been observed for ions of m/z 414 and m/z 614, respectively, obtained from perfluorotributylamine, well in excess of the normal value of 3m, where m is the ion mass. At the highest mass resolution observed, peak widths at half maximum are but 13.4 x 10(-6) u.
