New build and trial system now available20 July 2021
A new update (build 703) is now available, free to all current users – together with our new trialware system. You can now update your own version, or try PoreXpert for yourself for the first time, without any intervention from us – just go to the new software download page. The downloaded software will automatically adapt to whether you are a current user with a licence dongle, or a new user.

Effect of distorting a membrane21 June 2021
One of the last checks of PoreXpert v2 build 700, due at the end of June, has been to try it on filters and membranes. Here is an extract from a pre-formatted pdf report of the test, available in 6 different languages, showing a distortion giving rise to a reduction to 80% of original size of all voids above 0.88 μm within a membrane, characterised by a Porolux 1000 porometer. As a result of the distortion, the absolute permeability reduces from 0.702 mD for air at 25 °C and 1 atm pressure to 0.292 mD for water at 25 °C.

The United States Patent Office has accepted Application No. 16/753539 in the name of PoreXpert Limited : Pore Analysis .
Collapse tab6 April 2021
A new additional upgrade to the Targeted Modification tool is a Collapse tab, which reduces the size of all voids within a given range to the minimum size of the selected range. This new option is useful for calculating the endpoints of wetting phase relative permeability, in the presence of a non-wetting phase such as water or brine in an oil-wet rock or air in water-saturated soil.
Targeted modification15 March 2021
Targeted modification operations allow the geometry of specific voids to be changed, to simulate properties such as sample compression, ageing and relative permeability. A current major consultancy has required extensive sequential use of that tool, and in the process the algorithm has been over-hauled in terms of its background update of geometric variables. It also now outputs the resultant porosity in the Home (Operations list) page. These improvements, amongst several others, will be included in the next free update available to all current users, currently scheduled for May 2021.

New intermediate tutorial10 February 2021
In response to one of our users, we have written a new intermediate level tutorial entitled Modelling your own sample. You can access it at https://www.porexpert.com/help2/index.html?modelling-your-own-sample.htm . It also explains how to view the simulated void structure of high porosity samples. With good wishes to all visiting this website, and the hope that soon Covid-19 will cease to impact on all our endeavours.
New advanced tutorial21 December 2020
We now have a significant number of researchers and product development scientists using PoreXpert version 2. However, Covid-19 restrictions have prevented us from organising training courses. Therefore we have posted a new advanced tutorial at https://www.porexpert.com/help2/index.html?artefacts-and-stochastic-realisations.htm. It is required reading, as it explains how to avoid false results generated by the program itself – artefacts. We wish all our users the best possible Christmas and New Year in these very difficult times.
Free key fob3 December 2020
Would you like to easily identify your PoreXpert or PoreXpand Sentinel hardware dongle, or just have a colourful key fob for other purposes? We are offering free key fobs to all current PoreXpert and PoreXpand users, and also anyone who has registered on the website with details of their scientific interests – a maximum of two fobs per person, or four per institution. So just go to the Contact Us page to register, or, if you a current user or have already registered, email us at firstname.lastname@example.org .
