The following topics provide guidance on how to use porometry data with PoreXpert, if you are running with a demonstration copy of PoreXpert you will not be able to open the raw data files, but you will be able to open the poreXpert file that starts the tutorial. The tutorial assumes that you are using the PoreXpert for POROLUX version and therefore the unit cell size is restricted if you have a more powerful version of PoreXpert, you are welcome to follow the tutorial using a larger unit cell size. As larger unit cell sizes increases the stability of the calculated properties such as permeability.

 

For PoreXpert to be able to process Porometry data the sample files must include the wet and dry curve data. The wet curve data is when the proprietary wetting fluid is being pushed out of the sample by increasing gas pressure. The dry curve is a second run over an identical pressure range to determine the gas permeability and is essential for PoreXpert as both sets of data need to be combined for PoreXpert to use Porometry data. There are example Porometry files located in the PoreXpert Example Files folder.

Once the above two operations have been performed by PoreXpert, it is possible to follow any of the other tutorials, for the software, this is dependant on the version of the software being used.
