The Illinois State Geological Survey (ISGS), a division of the Prairie Research Institute at the University of Illinois at Urbana-Champaign, has expanded its analytical capabilities by adding a new energy dispersive X-ray fluorescence (ED-XRF) facility. This new facility includes a custom Rigaku NEX Cartesian Geometry system with a high-performance silicon drift detector. The facility is now accepting samples for analyses in a wide variety of applications related to geology, archeology, engineering, and the environmental sciences.
 
The laboratory can quantify elemental concentrations of sodium to uranium in solid, powdered, or pelletized samples at levels from parts per million to percentages. Bulk (solid) sample analysis is nondestructive and provides a quick scan of an object for elemental composition. This type of analysis is ideal for solid materials such as rocks or archeological artifacts. Powdered and pressed pellet methods can be used when greater analytical accuracy is desired. The pressed pellet approach is especially useful for analysis of sodium and magnesium in carbonate samples. Samples can be also be analyzed under vacuum or a helium atmosphere to improve the detection of sodium and magnesium.
