PoreXY, the brand new data pre-processor for PoreXpert, allows you to trim and thin data to make it more statistically representative for modelling, as well as giving you the solid phase bulk modulus (compressibility) of your sample.

Our consultancy services


We offer use of our own PoreXpert software for companies who have a problem to solve, but do not wish to spend time learning PoreXpert themselves.

Projects range from short-term modelling of a few characteristic curves measured by the client, to longer term use including development of bespoke features in the software, and supply of the specialised software to the client.

Learn more about consultancy

By arrangement with the University of Plymouth, UK, we offer a range of measurements as stand alone,  for input into PoreXpert or for validation of modelling outputs.

Projects range from individual experiments to major surveys of a range of samples of different manufacturing characteristics, different weight losses, etc.

… a comprehensive tool for modelling porosity and fluidics in porous structures

extract from RSC Chemistry World review

This software has enabled us to improve our sintered aluminium test piece, and we have featured some virtual reality structures in our new company brochure.

Dr Mark Cross, Chemical Technology Manager, Ultraseal International, Coventry, UK

…we are very impressed with your work. We’ve sent samples to other groups for analysis and none have even come close to the information you’ve given us.

Jeffrey Alvaji, QuestAir Technologies Inc., Canada

…congratulations for new version of your software. It is very user-friendly!! I think it will increase consistently the use of model worldwide

Prof. Francesco Morari, Università di Padova, Italy

You and your team have produced a great tool – which seems to only improve with time

Walt Pavlakovich, General Manager Tech. Service, World Minerals Inc., California

I have gained further insight on my research work after undergoing the training course which will be very helpful in moving forward. It has a lot of capacities to be explored based on the user’s needs, and is very user friendly!
