Who Should Attend?
Technicians, analysts, lab managers, researchers, and anyone needing to operate and/or interpret and understand AutoChem results should attend this 3-day course. The course will utilize the latest standard AutoChem model, but most course material is also applicable to users of previous models (i.e. – AutoChem 2910). 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 AutoChem components and how they operate
- Sample preparation, including sample quantity and sample loading
- Hands-on analyses, including pulse chemisorption, TPR, TPD, Heat of Desorption, and experiments using the vapor generator
- An overview of chemisorption theory, including temperature-programmed experiments
- Utilization of all AutoChem software features, the programming of sample files, and the management of gas, vapor, and active metal defaults to efficiently obtain accurate and reproducible data
- The customization and editing of all available reports and graphs, including data exporting
- Data reduction, including the application of TCD calibrations as well as peak editing and fitting
- Operator Maintenance – meet with a member of our Service Department to discuss calibrations, troubleshooting and user-maintenance

Background
The AutoChem is a fully automated chemisorption analyzer that can conduct a comprehensive array of highly precise studies of chemical adsorption (chemisorption) and temperature-programmed reactions. It can acquire valuable information about the physical properties of catalysts, catalyst supports, or other materials. It can determine catalytic properties such as percent of metal dispersion, active metal surface area, acid strength, surface acidity, distribution and strength of active sites, BET surface area, and more. The AutoChem performs pulse chemisorption, temperature-programmed reduction (TPR), desorption (TPD), oxidation (TPO), and reaction analyses automatically.
