Meaning
Elemental analysis techniques that measure the secondary x-rays emitted from a material when it is excited by a primary x-ray source allow for the rapid identification of chemical composition. Usage of x-ray fluorescence provides a non-destructive way to verify the alloy type and the presence of hazardous substances in a sample. This method is used extensively in the scrap metal industry and for screening electronics for compliance with environmental regulations.
The measurement takes only a few seconds and requires minimal sample preparation.
Fluorescent Analysis
Handheld or desktop units fire a beam at the object and analyze the resulting energy spectrum. Each element produces a unique signature that the system uses to calculate its concentration.
Metal Screening
Quality control teams use this tool to ensure that the correct materials are being used in production. x-ray fluorescence can distinguish between different grades of stainless steel or aluminum in real time. This capability prevents the accidental use of the wrong alloy, which could compromise the strength of a finished part. The technology is also used to check for the presence of lead and other restricted materials in consumer goods.
Because it is non-destructive, the tested parts can be returned to the production line immediately after analysis.
Measurement Speed
Efficiency in the warehouse is improved by the ability to test materials on the spot. x-ray fluorescence is the fastest method for the elemental verification of bulk materials in a commercial setting.
