T/FJEMIA 6-2022 Rapid screening of copper, zinc, lead, nickel, chromium and arsenic in soil by portable energy dispersive X-ray fluorescence spectrometry (English Version)
When atoms of elements contained in soil samples are irradiated by high-energy X-rays, they emit a characteristic X-ray spectrum with a certain energy. According to the principle that the pulse height of the output signal of the semiconductor detector is proportional to the energy of the incident X-ray photon, when the semiconductor detector detects the characteristic X-ray spectrum of the soil sample, each channel of the multi-channel analyzer counts simultaneously, allowing simultaneous measurement of multiple elements. Conduct qualitative and quantitative analysis by detecting different characteristic X-ray energy positions and intensities.
