Who Should Attend?
Technicians, analysts, lab managers, researchers, and anyone needing to operate and/or interpret and understand Gemini results should attend this 2-day course. The course will utilize the latest Gemini model, but most course material is also applicable to users of previous models (i.e. – Gemini 2360). The course is extremely beneficial to the entry-level operator and moderately experienced users wishing to expand their capability. Prior hands-on experience with the instrument is helpful, but not required.
Curriculum
- The Gemini components and how they operate
- Sample preparation, including sample quantity, sample loading, FlowPrep and/or VacPrep operation, degas parameters, and the use of glass beads to balance free space
- Hands-on operation, including BET analyses and full adsorption isotherm collection using nitrogen
- An overview of physical adsorption theory, including surface area, mesopore and micropore characterization
- Utilization of all Gemini 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, and DFT
- Operator Maintenance – meet with a member of our Service Department to discuss troubleshooting and user-maintenance

Background
The Gemini Series of surface area analyzers rapidly and reliably produces accurate and repeatable surface area and porosity results. It can determine single and multipoint BET and Langmuir surface areas, total pore volume, micropore analysis by the t-method, and much more. The design of the Gemini provides unique capabilities as many error sources inherent in traditional static volumetric instruments are eliminated through common mode rejection promising more accurate and stable measurements. An ideal tool for teaching, research, and quality control environments, the Gemini permits low to high surface area measurements without requiring exotic gases such as argon or krypton.
