Who Should Attend?
Technicians, analysts, lab managers, researchers, and anyone needing to operate and/or interpret and understand SediGraph results should attend this 3-day course. The course will utilize the latest SediGraph model, but most course material is also applicable to users of previous models (i.e. – SediGraph 5100). The course will be very beneficial to an entry-level operator but should also prove informative for moderately experienced users wishing to expand their capability. Prior hands-on experience with the instrument is helpful, but not required.
Curriculum
- SediGraph components and how they operate
- Sample preparation and dispersion, including sampling, choosing an appropriate analysis liquid and surfactant, the stages of dispersion, dispersion techniques, and sample loading
- An overview of sedimentation theory, including Stokes Law, particle size distribution calculations, and SediGraph operational theory
- Utilization of all SediGraph software menus and screens to efficiently obtain accurate and reproducible data
- MasterTech autosampler installation and operation
- The customization and editing of reports and graphs, including reference and specification reports, plot overlays, data exporting, and SPC reports
- Data reduction, including the verification of dispersion quality, sample size range, concentration, and analysis liquid selection
- Operator Maintenance – meet with a member of our Service Department to discuss troubleshooting and user-maintenance

Background
The SediGraph determines particle size by using the highly accurate and reproducible sedimentation technique, which measures the gravity-induced settling rates of different size particles in a liquid with known properties. The instrument measures mass by X-ray absorption and particle size by sedimentation, therefore no modeling is required. This is a simple yet extremely effective technique for providing particle size information for a wide variety of materials.
