Abstract:
A signal intensity based on a total ion current signal or the like is calculated from mass spectra obtained by a normal mode of mass spectrometric analysis. When the signal intensity has exceeded an intensity threshold, the beginning time T 0  of a chromatogram peak is estimated from that signal intensity as well as one or more previous signal intensities. An MS 2  execution permission-beginning time Ts is calculated by adding, to the beginning time T 0 , a delay time Tdelay determined front a half-value width of the peak estimated according to an LC separation condition. At or after the point in time where the actual time passes Ts, a peak which satisfies a precursor-ion selection condition is selected on a mass spectrum obtained by the mass spectrometric analysis. Then, an MS 2  analysis with the m/z of the selected peak as the target is immediately performed to obtain an MS 2  spectrum. By appropriately determining the delay time Tdelay, a high-sensitivity MS 2  spectrum for a target component can be obtained when the concentration of the target component has become sufficiently high, and the accuracy of a qualitative determination or structural analysis of the component is thereby improved.

Claim (Index 3):
The mass spectrometer according to  claim 2 , wherein:\n the time determiner determines the delay time based on an estimated value of a half-value width of the peak on the chromatogram.
