Note: In order for this operation to be valid, both traces must have
the same sampling frequency.
Multiply Traces
To multiply two traces,
1. In the Chromatogram Window, do a right mouse click
and select Operations followed by Multiply.
2. Select the first trace by clicking the mouse on the
chromatogram or trace.
3. Select the trace to be multiplied by the first by
clicking on the 2nd trace with the mouse. The result
trace will appear in the window. For the multiply
operation, the units of the resulting trace are <trace 1
units> x <trace 2 units>.
Divide chromatograms or traces
To divide two traces,
1. In the Chromatogram Window, do a right mouse click
and then select Operations followed by Divide.
2. A prompt will appear in the window Click on 1st
trace. Select the first trace by clicking the mouse on
the chromatogram.
3. A second prompt Click on 2
nd
trace will appear.
Select the trace to be divided into the first by clicking
on the trace with the mouse. The result trace will
appear in the window. The equation used to calculate
the result trace is as follows.
Where
p = the calculated point for the result trace at time t
y1 = a point from the first trace at time t
y2 = a point from the second trace at time t
