Sample Analysis via Energy Dispersive X-Ray Fluorescence (EDXRF)
Handheld Thermo Scientific NITON® energy-dispersive x-ray fluorescence (EDXRF) analyzers, commonly known as XRF analyzers, are able to quickly and nondestructively determine the elemental composition of:
● Metal and precious metal samples
● Rocks and soil
● Slurries and liquid samples
● Painted surfaces, including wood, concrete, plaster, drywall and other building materials
● Dust collected on wipe samples
● Airborne heavy elements collected on filters
Thirty or more elements may be analyzed simultaneously by measuring the characteristic fluorescence x-rays emitted by a sample. NITON XRF analyzers can quantify elements ranging from magnesium (element 12) through uranium (element 92), measuring x-ray energies from 1.25 keV up to 100 keV. These instruments also measure the elastic (Raleigh) and inelastic (Compton) scatter x-rays emitted by the sample during each measurement to determine, among other things, the approximate density and percentage of the light elements in the sample.
