Adsorption & Porosimetry Analysis Service
The characterization of surface area, pore structure, and adsorption behavior is fundamental to understanding the physical and chemical properties of materials. Porosity and adsorption phenomena determine how gases, vapors, or liquids interact with solid surfaces and directly influence a material's performance in catalysis, filtration, pharmaceuticals, energy storage, and environmental applications.
Adsorption and porosimetry analysis provides quantitative insights into the relationship between surface chemistry, pore geometry, and material functionality. By combining advanced measurement techniques such as chemical adsorption, dynamic vapor sorption, and mercury intrusion porosimetry, scientists can accurately determine key parameters including surface area, pore size distribution, pore volume, and adsorption isotherms.

Determines surface active sites and chemisorption capacity using static, dynamic, and temperature-programmed approaches (TPR, TPD, TPO). Provides insights into catalytic metal dispersion, reaction kinetics, and adsorption heat.
💠Dynamic Vapor Sorption (DVS) Analysis Service
Measures weight changes in a sample as a function of humidity or vapor concentration, enabling precise assessment of sorption isotherms, moisture uptake, desorption behavior, and diffusion kinetics.
💠Water Activity Analysis Service
Quantifies the free water activity (Aw) within a sample, reflecting microbial growth potential, chemical stability, and product shelf life, particularly relevant for food, pharmaceuticals, and biological materials.
💠Capillary Flow Porometry Analysis Service
Determines pore size distribution, mean flow pore diameter, and permeability by analyzing fluid displacement through porous membranes or filters, supporting applications in filtration, coatings, and separation media.
💠Micropore Measurement Analysis Service
Utilizes gas adsorption (e.g., N₂ or CO₂) at cryogenic temperatures to characterize pores smaller than 2 nm, providing accurate BET surface area and pore volume data for catalysts and adsorbents.
💠Mesopore Measurement Analysis Service
Focuses on pores ranging from 2–50 nm, using adsorption–desorption isotherms to reveal pore geometry and hysteresis behavior in ceramics, polymers, and composites.
💠Mercury Porosimetry Based Porosity and Pore Size Distribution Analytical Service
Applies controlled-pressure mercury intrusion to quantify porosity, pore size distribution, pore volume, and specific surface area across the 3 nm–360 µm range, ideal for dense or coarse materials.
