Other Applications

Educational
Since XRF is an important analytical method in chemistry and geology, many universities have XRF instruments as both a teaching and research tool. back to top

Paints and Pigments
Many paints and pigments contain metal dies that can be analyzed by XRF. One specific application is titanium dioxide and lead chromate respectively in white and yellow road paint. back to top

Si and Fe in Copier Toner
Si, Fe and several other elements are present in copier toner. The formulations vary widely, but all can be analyzed by XRF. back to top

Fe in Magnetic Recording Tape
Iron and other metals in recording tape are monitored by XRF. back to top

Ag and Br in Photographic Film and Plates
Silver is expensive and there is a lot of it on photographic film and plates. It can be measured without exposing the film. XRF is also used for measured silver in chemicals that are saved for recycling, and can monitor wastewater to ensure the silver levels are within legal limits. back to top

Fe and other Wear Metals in Nuclear Reactor Coolant
Nuclear reactor coolant must be continuously monitored for wear metals such as iron, since they indicate corrosion and wear within the reactor systems. Medium and high-resolution systems are used to make this measurement. This is also a successful on-line application. back to top

Chlorine in Cutting Fluids
Cutting fluids contain chlorine in fairly high concentrations, but it must be controlled for consistency. back to top

Sulfur in Paper Manufacturing
XRF has been used for monitoring sulfuric acid in white a black liquor used in paper pulp processing. back to top

S and Cl in Hydraulic Fluid
Sulfur and chlorine are present in hydraulic fluids at concentrations near 100 PPM. XRF has been used for this analysis. back to top
