SEC Setup Broad Range1 Calibration
Fig. 381
When you select Broad Range1 as the calibration method, the SEC
Setup will appear as shown below.
Enable Analysis
Click this box to enable SEC calculations for the current channel. Each
channel can have its own analysis conditions.
Molecular Mass Table
The Broad Range 2 method is a linear calibration method that does not
utilize the Molecular Mass Table. Enter values in the Calibration Data
area.
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.
