Application Summary
High sensitivity X-ray fluorescence spectrometer PHECDA series
"GB 5085 Identification of Hazardous Waste Identification Standard Toxic Substances Content Identification" stipulates the limit values of more than 20 toxic element substances. Due to the variety of solid waste. With the complex sample matrix, the variety of elements, the wide content range, the instrument pollution and other challenges, it is difficult to quickly quantitatively analyze the content of various solid waste toxic elements. Traditional XRF requires standard samples for quantitative analysis, and the diversity of solid waste makes it almost impossible to rely on standard samples to establish a standard curve.
Ancoren launched a complete application solution: a high-sensitivity X-ray fluorescence spectrometer with fast fundamental parameter method to detect the content of toxic elements in solid waste and hazardous waste. It is simple in sample processing and suitable for various solid waste samples.
Method Principle
（1） Hardware core technology
High Sensitivity X-ray Fluorescence Spectrometer（HS XRF®）
Monochromatic excitation
The background interference generated by the X-ray tube emission spectrum by sample scattering is reduced by 2 orders of magnitude.
Focused excitation
The intensity of fluorescence rays of the sample elements accepted by the SDD detector increased.
（2）Software Core Technology
Fast Fundamental Parameter Method（Fast FP®）
Operating Software
Mathematical model and database of the X-ray process are established.
The Matrix, spectral line interference, and background deduction will be calculated.
A few of reference samples to improve quantitative accuracy.
