Application: The Autosorb IQ-XR is a surface area and pore size analyzer using Alpha-s, BET, DR, Gurvich pore volume, Langmuir, t-plot (STSA), that uses gas adsorption techniques to characterize the surface properties of solid materials. It measures surface area, pore size distribution, and pore volume methods like NLDFT, QSDFT, GCMC, BJH, DH, DA, HK, SF, MP of a wide range of materials, including catalysts, adsorbents, and porous materials. It can also analyse fractal dimensions (NK, FHH), heat of adsorption. SPECIFICATIONS Model: Autosorb IQ-XR Pressure Range:Pressure Range: 1x10-7 to 760 Torr (p/p0 for N2 77K) Type of samples: Powder; Pellet
