Regional Geochemical Centre
Regional Analytical Facility
The Regional Analytical Facility (previously known as the Gregional Geochemical Centre) is located on the campus of St. Mary's University in Halifax, Nova Scotia as part of the department of Geology. The principal focus of the RAF is to utilize non-destructive analytical x-ray fluorescence (XRF) to determine elemental concentrations in environmental samples. Geologic samples are analyzed by crushing whole rocks into fine particles less than one-tenth of one millimeter in diameter. These powders then can either be pressed into flat pellets at high pressure or melted with a fluxing agent to form a glass like disk prior to analysis. Also, it is possible to measure loose powder or even liquid samples directly. We can typically analyze most elements down to the low parts per million levels using this technique.
