NOTE: If you stop an experiment without saving any
segments, no .DAT file is created.
NOTE: All instrument settings except Shots/Spectrum are
disabled as soon as you start acquisition in PSD mode, until
you stop the experiment. Make sure instrument settings are
correct before starting acquisition.
Acquiring PSD
segments
To acquire PSD segments:
1. In the Manual Laser Intensity/Sample Positioning
control page, select the same sample position from
which you acquired the precursor spectrum.
2. From the View menu, select Data Storage. Set
parameters as needed. See “Setting Data Storage
parameters” on page 6-14, for information.
Hint: Include a _PSD suffix when you name PSD data
files to help you distinguish them from non-PSD data
files. For example, type in Experiment1_PSD as the file
name. The complete data file name will be
Experiment1_PSD.DAT or Experiment1_PSD0001.DAT
(if Autosequence File names is enabled).
Selecting and
acquiring a
segment
3. In the PSD Acquisition Settings control page, select (click
on) the row that corresponds to the segment you want to
acquire.
4. To start acquiring, select Start Acquisition from the
Acquisition menu, or click .
5. Adjust laser intensity to optimize signal intensity. You
typically need higher laser intensity to optimize intensity
for segments with lower Mirror Ratio settings.
