X-Ray Fluorescence

X-ray fluorescence can be used to determine the elemental composition of the surface of a core sample.

An x-ray tube pointed at the core illuminates the sample with x-rays which are then absorbed by the atoms on the surface of the core. These excited atoms then release the energy as a characteristic photon during a process called fluorescence. The energy of the photon is specific to the element which released it.

*An X-ray Fluorescence sensor may not be provided with the MPL. The equipment is compatible with the Olympus Delta and Vanta handheld XRF sensor. For XRF measurements, the user will need to supply the sensor.
