Enable Analysis
Click this box to enable SEC calculations for the current channel. Each
channel can have its own analysis conditions.
Molecular Mass
For each calibration peak, enter a Molecular Mass that is representative
of the calibration standard peak.
Average Time (min)
Enter the time in minutes of the calibration standard peak. If you have
used the graphical Define SEC Peaks command, the peak times will be
entered already for you. Note: the time is converted to seconds for
calibration and Molecular Mass calculations.
Time Slice
Select a time slice width (in seconds) for the calculations. The slice width
will determine the frequency of Molecular Mass fractions reported. If a
Slice Report is generated, it will be based on the slice width you select
here. The software will force this number to be an integral of the data
collection rate during the analysis.
Baseline Start and Stop Times
The baseline start and stop times (in minutes) can be entered manually
or selected graphically using the SEC buttons on the chromatogram
toolbar.
Results Range Start and Stop
One or more ranges of the chromatogram must be defined to be used in
calculation and reporting of the Molecular Mass distribution. Each range
is determined by the results range start and stop values. The times (in
minutes) can be entered manually or graphically using a stored
chromatogram.
