Integration with
baseline
|
|
Abstract
Integration with baseline is performed by using
the “Peak analysis” tool of VoltaMaster 4. Firstly, the user determines
the baseline or lets VoltaMaster 4 do it automatically, then this
baseline is subtracted to the sample curve and the result curve
is processed to give the peak integration surface within two selectable
points. The positive surface (surface having a positive ordinate),
the negative surface (surface having a negative ordinate) and the
total surface are displayed and can be saved in a result folder
by clicking a Save button.
Experimental curve
The curve has been obtained from a Pot.
Cyclic Voltammetry (demonstration curve: No ODC 035.CRV). The curve
must show only one peak (use the Linear extraction tool between
point number 340 and 510).
Settings
A baseline determination by manual mode is selected.
Results
Conclusion
Peak integration with baseline is a post run
processing which can be used to integrate peaks on a user selected
baseline contrary to the “Processing – Integration” tool which integrates
only with a y=0 baseline.
