Analysis Title: X-Ray Fluorescence
Instrumentation: Niton XL3t GOLDD+ Handheld XRF
Theory of Operation:
• X-Ray Fluorescence is defined as “The emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays”. The phenomenon is widely used for elemental analysis of rocks, metals, and soil sediments.
Analytical Procedure:
Run a system check for the instrument to make sure that there is no error.
Run a blank to make sure there is no contamination.
Run a standard to check the calibration.
Adjust the analysis time for 150 sec.
Weight about 4 gm of a ground rock sample.
Put the sample in the sample cup and shake the cup to settle the fine grains down.
