  text: Characterization and application of (meso)porous materials often require information
    about the density of the respective samples. For example, the BET surface area
    is, by definition, normalized to the sample mass; hence, any comparison between
    samples of different composition needs to take into account their respective densities.
    Literature data on the densities of porous materials are scarce. Frequently, only
    bulk-phase densities are available which sometimes differ from those of porous
    samples, especially for amorphous systems, such as silica or carbon. The apparent
    density, i.e. the density of the sample excluding the gas-accessible pore volume,
    is typically determined by helium gas pycnometry utilizing specialized pycnometers.
    We demonstrate how to obtain the same data from standard N2 physisorption measurements
    as part of the regular measurement routine. We evaluate the method by reference
    measurements utilizing a non-porous reference sample (glass rod) to confirm the
    validity of the method. Then we present results on apparent density measurements
    of several mesoporous silica materials (MCM-41, MCM-48, SBA-15, KIT-6), mesoporous
    carbon (CMK-3, -5, -8, -9), and a variety of mesoporous metal oxides obtained
    by nanocasting.
