469048 Measurement of the Density of Microporous Materials Needed to Convert Net Adsorption to Absolute Adsorption
Results for both helium and water pycnometry are presented for different hydrophilic and hydrophobic commercial pelletized materials which confirm that the density of microporous materials needed to convert net adsorption to absolute adsorption can be measured without the use of mercury.
The general conclusions that can be drawn are that helium pycnometry provides reliable results while water pycnometry requires careful pre-treatment of the samples in order to yield the correct densities.
