Accumulating or
saving the
segment
6. Evaluate the spectrum, then do one of the following:
• Click in the toolbar to accumulate the
spectrum. You can accumulate as many spectra
as needed. When the accumulated spectrum is
acceptable, click on the Accumulated trace, then
click .
• Click in the toolbar to add the segment to the
.DAT file. After you save the segment, the Saved
check box in the segment list is checked.
• If the current spectrum does not contain significant
fragment ion signal and you do not want to
accumulate or save the spectrum, acquire
remaining segments as described below.
Selecting and
acquiring
remaining
segments
7. Repeat step 3 through step 6 to collect remaining
segments. You can collect segments in any order, and do
not have to acquire all segments in the list. You can also
acquire multiple segments with the same Mirror Ratio.
NOTE: Segments are listed in the Data Explorer
software in the order in which they are acquired. If
segments with duplicate Mirror Ratios are contained in
the file, the software uses the last acquired segment
when it generates the composite spectrum.
Reacquring a
segment
8. To reacquire a segment:
• Select the segment to reacquire.
• Click . A new row is added to the end of the
segment list and contains the settings from the
selected segment.
• Set parameters as needed.
• Repeat step 3 through step 6.
Stopping the
experiment
9. When you have acquired all necessary segments, select
Stop Experiment from the Instrument menu. The
PSD data file is closed.
