Abstract
The invention relates to a method of derivina improved data from a mass spectrometer. The method includes operating the mass spectrometer in a mode enabling quantitation; assigning a threshold value for the total ion current (TIC) above which at least MS and/or MSMS data is desired; and triggering the mass spectrometer out of the mode enabling quantitation into at least an MS and/or MSMS mode when said TIC rises above the threshold but triggering only at such time at or after a confirmed TIC maxima has been reached.
