Xtended Pressure Sorption Analyzer Dili micromeritics* The Science and Technology of Small Particles™

Superior Performance Under Extended Pressure The fuel cell and its chemical energy source, hydrogen, have received much recent attention as a promising long-term solution to the world’s energy needs. Developing storage technologies involving advanced materials and the conversion of hydrogen to useful forms of energy are of critical importance. A fundamental understanding of hydrogen physisorption/ chemisorption processes and adsorption/ desorption kinetics is needed to optimize hydrogen uptake and release capacity rates. Knowledge of chemical reactivity and material properties, particularly...

The ah new, fully automated ASAP 2050 is an essential tool for measuring adsorption isotherms up to 10 atmospheres. The ASAP 2050 also allows the user to collect traditional isotherms for determining surface area and porosity. Catalysts - Active surface area and porous structure of catalysts have a great influence on production rates. Limiting the pore size allows only molecules of desired sizes to enter and leave, creating a selective catalyst that will produce primarily the desired product. Adsorbents for Pressure Swing Adsorption - The adsorption capacity of alkaline-exchanged zeolites...

Hardware Versatility ASAP 2050 Hardware Advantages Programmable two-station degas system Dual cold traps The ASAP 2050 uses two independent vacuum systems, one for sample analysis and one for sample preparation. This allows preparation and analysis to proceed concurrently without the inherent delay found in single vacuum system analyzers that must share a pump. Moreover, independent systems completely eliminate the possibility of cross-contamination between the degas and analysis manifolds. Stainless-steel sample tube (designed for analysis pressures up to 10 atmospheres) A two-station...

Dedicated gas inlet for degassing samples Dedicated helium gas port ASAP Reference Materials Lanthanum Penta-Nickel Lanthanum nickel (LaNi5) is a well-known alloy that readily forms hydrides. This reference material is recommended for use with the ASAP 2050 to demonstrate the formation and characterization of hydrides. This material is ideally suited for use with the pressure composition isotherm report. Silica-Alumina Silica-alumina is a typical porous, high surface area reference material. The surface area of the silica-alumina typically exceeds 200 m2/g and the pore size is a nominal 100...

Software and Reporting Versatility ASAP 2050 Software Features The easy-to-use ASAP 2050 software utilizes a Windows® interface that includes Wizards and applications to help plan, launch, and control the analysis. You can collect, organize, archive and reduce raw data, and store standardized sample information and analysis conditions for easy access during later applications. Finished reports may be generated to screen, paper, or data transfer channels. Features include cut-and-paste graphics, scalable-and-editable graphs, and customizable reports. Additional capabilities include: • Degas...

The ASAP 2050 model includes: • Repetitive Isotherm Cycling • DFT (Density Functional Theory) • Single- and Multipoint BET (Brunauer, Emmett, and Teller) surface area • Langmuir surface area • Temkin and Freundlich isotherm analyses • Pore volume and pore area distributions in the mesopore and macropore ranges by the BJH (Barrett, Joyner, and Halenda) method using a variety of thickness equations including user-defined, standard isotherm • Pore volume and total pore volume in a user-defined pore size range • F-Ratio plots that illustrate the difference between theoretical and experimental...
