Technical Information: Microhole Analysis

A reliable micro-pore analysis method using nano-order adsorbed molecules as probes!

The theories for analyzing micropores include t-plot, HK, SF, DR-plot, NLDFT, and GCMC methods. t-plot and DR-plot are used to calculate pore volume and internal/external specific surface area, while HK, SF, NLDFT, and GCMC are effective methods for calculating micropore distribution. Micropore analysis theory is not as straightforward as adsorption theories for planar adsorption or mesopores, due to the short distance between pore walls and adsorbed molecules. Pore shapes are assumed to be cylindrical or slit-like, and it is necessary to select atomic or adsorbate parameters for the pore walls. We provide detailed information on our website. Please take a look. *For more details, please refer to the related links or feel free to contact us.*

Technical Information: Meso-Macro Pore Analysis

Information on particle analysis and particle analysis devices! Introduction to meso-macro pore analysis.

The analysis theories for mesopores include BJH, CI, DH methods (cylindrical type), and Innes method (slit type). These are calculated based on the capillary condensation theory (Kelvin equation) and are generally applicable to pore diameters of 2 nm or larger. We provide detailed information on our website. Additionally, we have published a table showing the relationship between relative pressure and pore radius. Please take a look. *For more details, please refer to the related links or feel free to contact us.*
