Nanoscale Characterization Facility - Indiana University, Department of Chemistry

BET Physisorption Analyzer


The ASAP 2020 system includes the degas and N2 adsorption-desorption systems which allows a full range of surface characterization analyses with automatic settings. It is equipped with six analysis gas inlets and a standard 1000-mmHg transducer for analysis of most routine samples, and is able to tailor the system to precisely fit your needs. The ASAP 2020 includes a powerful data reduction software to provide a variety of easy-to-interpret report options.It has the capability to collect data over a prescribed segment of the pressure range, or to perform adsorption and desorption analyses over the entire pressure range, providing extensive surface area and porosity information.


BET Physisorption Analyzer usage is $10/measurement (may include one or two samples). The users must log into the log book and the individual Excel sheet prior to using the instrument for billing purposes. The log book comments will help in assessing a possible malfunction which may occur during the user’s time.

There will be no direct charge for time expended by the director while initiating a project, training new users or any sort of consultation. It is expected, however, that a significant effort by the director will be acknowledged by such things as authorship, inclusion in grants and public presentations, etc.
