Create DHA Calibration

Create DHA Calibration dialog

This dialog is displayed when you click the Create DHA Calibration… button in the DHA Settings. The table contains the list of detected n-Paraffins from the measured known sample. The dialog allows you to manually adjust the retention times of particular compounds.

The main purpose of this dialog is to enter the retention times of Methane, Ethane, Propane, and n-Butane which you may have measured in a different chromatogram.Starting from the n-Pentane paraffin, the retention times are automatically added.

The minimum number of n-Paraffins in your known sample is 6 and the maximum is 11. If this condition is not met, an error dialog is displayed:

The opened n-Paraffins standard has to contain 6 to 11 peaks.
