Overview

Overlapping peak detection ranges

To accommodate spectral peaks that occur on the boundary of two peak detection ranges, the software creates detection ranges that overlap (Figure 3-2).

Figure 3-2 Overlapping Detection Ranges

If a peak occurs in an overlapping range (for example, Peak B in Figure 3-2), the software detects the peak using the settings from the detection range within which the entire peak occurs (Range 2 in Figure 3-2).

If a peak occurs completely within two ranges (for example, Peak D in Figure 3-2), the software uses the settings from the higher m/z detection region (Range 4 in Figure 3-2).

For PSD data, the mass-time correlation is different from that of standard TOF spectra. Therefore, resolution-dependent settings are not supported for PSD data.
