Basic (FREE) Edition.
The Basic Edition will be sufficient for many applications, such as short teaching demonstrations and many routine research applications.

The Basic Edition is sufficient for your needs if the following limitations are not a problem for your application:

  • maximum number of adsorbing surfaces present are limited to two.
  • maximum number of ions involved (besides H(+) and OH(-)) are limited to two.

Extended Edition (also FREE): Serial Number is required via "Add to Cart". It is the same as the Basic Edition, but no limitations are applied. IExFit Extended Edition will allow you to create large and complex models with any number of competitive ions involved, any number of adsorption surfaces involved, and any number of minerals involved.


This software is written in C#. It uses the .NET framework.
