In April 1993, Micromeritics introduced DFT V1.00, the first commercially
available software package offering a practical method to routinely analyze
experimental adsorption isotherms using methods based on modern theoretical
It was the culmination of an investigation by Micromeritics' scientists J.P.
Olivier and W.B. Conklin into a method by which the power of density functional
theory (DFT) could be utilized by any researcher or laboratory technician with a
Today, Micromeritics continues work in the area of isotherm data analysis
with the introduction of a new series of NLDFT models for characterizing porous
carbons. These new models are based on recent work by J. Jagiello and J.P.
Olivier. The set also includes the new 2-D models, first described in the
November 2009 edition of the Journal of Physical Chemistry. Another set of
recently introduced models provide researchers with additional options for
characterizing their carbon materials at either 77K with argon or 87K with
The Micromeritics DFT/NLDFT model set is the largest library commercially
available and continues the Micromeritics trend of innovation and excellence in
the area of gas adsorption technologies. All new NLDFT models are available at
no cost to users of Micromeritics' DataMaster, ASAP® 2020, ASAP® 2420, TriStar®
II 3020, and Gemini® VII 2390.
