On the home screen shown below open the File menu and click on Open.
Open the tutorial sample file located in the tutorial files folder for PoreXpand. The screen will now display the following:

Now click on the Sample dropdown menu. The dropdown display shows the properties of the mercury read from the data file and basic information on the sample. There is some additional experimental information required for the calculations, which cannot be read from the experimental data files. The following figure shows an expanded view of the sample information. You need to scroll down to see all of the expanded sample information.

The information required to perform a complete compression correction is (i) the penetrometer and assembly weight, which is calculated once the penetrometer has been sealed with the sample by subtracting the sample weight from the total assembly and sample weight, and (ii) the weight of the penetrometer with sample filled with mercury at the end of the low pressure stage of the experiment, to allow the software to calculate the volume of the sample, by comparing the filled penetrometer weight with the blank filled penetrometer weight.
Enter the following details into the text boxes shown above, namely:
Penetrometer + assembly weight: 65.3229 g
Penetrometer + assembly + sample + mercury weight: 130.7231 g
You can now continue onto the next stage of the PoreXpand tutorial, performing the blank correction.
