Comparison
PoroCheck is a cost effective and easy-to-use software because it utilizes existing lab equipment to investigate porous materials. No additional training cost are necessary, no additional instrument maintenance or spare parts are needed. It also allows to investigate samples on an occasional basis because of its immediate return on investment. Operating cost are minimal, no toxic compounds (like Hg) or expensive liquified gases (like N2,Kr) are needed.
PoroCheck uses a determined porous structures in their native state and not in high vacuum or under extreme pressures. It allows to investigate all types of porous structures: rigid, swollen, adsorbed, partially filled, etc. The PoroCheck method takes the dynamics of pore access into consideration even down to a molecular level. Therefore only pores are investigated which are truly accessible; bottleneck pores or pore without external access are not screened.
The dynamic range of pore sizes is huge, spanning from about 5 Å to over 6 000 Å in a single experiment. Results are obtained fast and reliably (see theory) and can be expressed in many ways.
The software runs on any Win32 operating system and makes pasting results into own reports really easy (using the Windows clipboard intelligently). Both graphical and numerical results and data tables can be copied to any Windows application.
