Comprehensive Applications

Powder (Fine particles and coarse particles)ɹ−Qualitative and Quantitative Analysis of Rock−
The analysis of powder samples is a typical application of X-ray fluorescence. The sample is either pressure molded or placed in a sample
container for analysis. The figure below shows an example of the qualitative and quantitative analysis of rock reference material by Na to U.
Accurate quantification is possible even without a standard sample. Light elements can also be measured with high sensitivity by vacuum
atmosphere measurement.

Liquid, Slurry and Emulsionɹ−Heavy Elements in Waste Oil−
To measure a liquid sample, simply add it to a sample cell with film on the bottom. This method is effective for the detection and quantitation
of additive components and worn metals in aqueous solutions, organic solvents, or oils.
As shown below, the system achieves adequate detection of heavy elements in waste oil at ppm levels.
