Who Should Attend?
Technicians, analysts, lab managers, researchers, and anyone needing to operate and/or interpret and understand ASAP 2420 results should attend this 3-day course. Most course material is also applicable to ASAP 2405 users. The course is extremely beneficial to the entry-level operator as well as moderately experienced users wishing to expand their capability. Prior hands-on experience with the instrument is highly beneficial, but not required.
Curriculum
- The ASAP 2420 components and how they operate
- Sample preparation, including sample quantity, sample loading, and degas parameters
- Hands-on analyses, including BET analyses using both nitrogen and krypton, full adsorption & desorption isotherm collection using nitrogen, and a micropore analysis including free-space determination and subsequent sample port degassing
- An overview of physical adsorption theory, including surface area, mesopore & micropore characterization
- An overview of DFT/NLDFT theory
- Utilization of all ASAP 2420 software features and the programming of sample files to efficiently obtain accurate and reproducible data
- The customization and editing of all available reports and graphs, including reference and specification reports, plot overlays, data exporting, and SPC reports
- Data reduction, including BET, BJH, t-plot, DFT, and the use of the Physi ViewCalc tool.
- Operator Maintenance – meet with a member of our Service Department to discuss troubleshooting and user-maintenance

Background
The Micromeritics ASAP 2420 Accelerated Surface Area and Porosimetry System uses the gas sorption technique to generate high-quality data for research and quality control applications that require high performance/high sample throughput. The instrument can be used to characterize the active and support surfaces of catalysts and to determine the high surface areas of adsorbents or the microporosity and hydrogen storage capacity of various nano materials. Materials with low surface areas such as powdered metals, glass fibers, and natural organic materials can also be analyzed.
