摘要: Selectivity of a measurement from mass spectrometer is improved by selecting an extracted ion current window for the after data acquisition. A plurality spectra are acquired over period time. first selected and intensity as function time calculated using window. second signal-to-noise ratio compared with intensity. If greater than ratio, used measurement.
