Vapor Pulse Calibration

Use to associate analysis data with a vapor pulse calibration file. This allows the conversion of pulse peak areas to the quantity of vapor adsorbed for each peak. The calibration can be performed either before or after performing the analysis. A single calibration file can be used with multiple analysis files.

Specific selections and entries shown in this table are only applicable when using Micromeritics samples. Make the necessary adjustments when using non-Micromeritics samples.

1. Go to File > Open > Sample information.
2. Enter a calibration file name (.CAL).
3. Click OK, then click Yes to confirm.
4. Complete the remaining fields on the Sample Description window, as needed.

If the window displays in Basic presentation, click Advanced in the view selector drop-down at the bottom of the window.

5. Select the Analysis Conditions tab.
6. Select AutoChem III  in the View conditions for drop-down list.
7. Click Insert, then select Vapor Pulse Calibration.

8. Complete the dialog box according to this table:
