Save Conditions

• Save first spectrum to pass acceptance criteria—
The first spectrum that meets the selected
acceptance criteria is saved. Acquisition is performed
on each search pattern position* until a spectrum
passes or until the end of the search pattern is
reached. If no spectra pass acceptance criteria, no
data file is saved. All search pattern positions may
not be analyzed.
Example: Number to Acquire is automatically set to
1, Number of positions in .SP=20, the number of
positions analyzed is equal to the position number in
which the first passing spectrum is found. One .DAT
created. If no spectra meet criteria, no .DAT created.
• Save best—Automatic Sample Positioning is
required with this mode. Acquisition is performed on
all search pattern positions. All Acceptance Criteria
are evaluated, and the passing spectrum with the
best Signal-to-Noise result is saved. If no spectra
pass acceptance criteria, no .DAT created.
NOTE: In this mode, acquisition moves to the next search
pattern position for every acquisition, even if acceptance
criteria pass.
Example: Number to Acquire is automatically set to
1, Number of positions in .SP=20, the number of
positions analyzed=20. One .DAT created containing
the best spectrum acquired. If no spectra meet
criteria, no .DAT created.
* If Use Automated Sample Positioning is disabled, acquisition is performed on the positions you
manually select.
