The PSD Processing dialog box is displayed
(Figure 8-2) and lists all segments contained in the PSD
.DAT file in the order in which they were acquired with
associated Mirror Ratios and Max Stitch Masses.
Figure 8-2 PSD Processing Dialog Box
The Max Stitch Mass is equal to the Precursor Mass
times the Mirror Ratio. This value reflects the maximum
mass of the segment that will be included in the composite
spectrum. The mass range included in the segment is
approximately 15 percent higher than the Max Stitch
Mass. Optimum focus and resolution is achieved for
fragment ions close to this mass.
