Micromeritics ASAP 2020 PLUS Adsorption Analyzer

GENERAL INFORMATION | STANDARD OPERATING PROCEDURE

Location: Havemeyer 224

The Micromeritics ASAP 2020 PLUS is a high-performance gas adsorption analyzer used to measure surface area, pore size distribution, and pore volume of porous and powdered materials. This instrument employs static volumetric gas adsorption techniques using nitrogen, CO2, and other probe gases to generate adsorption and desorption isotherms. The system is ideally suited for gas adsorption analysis of microporous (0.35 to 2 nm) and mesoporous (2 to 50 nm) materials, delivering superior accuracy, resolution, and data reduction. Surface area is determined using the Brunauer-Emmett-Teller (BET) theory, while pore size distributions are calculated using methods such as Barrett-Joyner-Halenda (BJH), density functional theory (DFT), or other models depending on pore characteristics. The system is equipped with an ISO Sub-ambient temperature controller utilizing thermoelectric cooling based on the Peltier principle, capable of maintaining constant temperatures between -5°C and 80°C for versatile adsorption analysis.

Standard methods or user-customized protocols can be used to characterize a wide variety of materials including adsorbents, catalysts, zeolites, metal-organic frameworks (MOFs), activated carbons, ceramics, active pharmaceutical ingredients (APIs), excipients, and nanomaterials. Applications include quality control of porous materials, optimization of catalyst supports, development of gas storage materials, analysis of filtration media, and fundamental studies of adsorption phenomena.
