Obtaining Statistics of a Selected Region on the
Chromatogram
For each trace, you can view specific statistics for a selected region on the
chromatogram. Selecting a region on the chromatogram creates the Region
Statistics table, which displays the following data:
Trace name — the type of trace. Only traces selected in the Runs/Traces
table appear in the Region Statistics table.
Units — the trace’s units.
Color
Left X (min) — the value of the left x-axis point of the selected region,
specified in the selected x-axis units (min/ml/CV).
Right X (min) — the value of the right x-axis point of the selected region,
specified in the selected x-axis units (min/ml/CV).
Delta X — the range of the x-axis (right x-axis – left x-axis) of the selected
region, specified in the selected x-axis units (min/ml/CV).
Left Y — the value of the trace on the left y-axis point of the selected
region.
Right Y — the value of the trace on the right y-axis point of the selected
region.
Min Y — the minimum y-axis value of the specific trace within the region.
Max Y — the maximum y-axis value of the specific trace within the region.
Average Y — the average y-axis of the specific trace within the region.
You can modify the selected region on the chromatogram or in the Region Statistics
table. Resizing the selected r
egion updates the values in the Region Statistics table.
You can also copy the statistics in the table and paste those data into a
spreadsheet. Closing the Region Statistics table clears the selected region on the
chromatogram.
