A650 X-ray Fluorescence Analyzer

The A650 X-ray Fluorescence Analyzer is a high-end analytical instrument developed by Jiapu Instruments after years of research, specifically designed for non-ferrous metals, ferrous metals, mineral processing, metallurgy, and geological industries.

Principle and Characteristics of X-ray Fluorescence Analysis

X-rays are used to bombard the sample, which then emits X-ray fluorescence upon excitation. The X-rays typically eject inner-shell electrons (K and L shells) from the atoms, creating vacancies that are filled by higher-energy outer-shell electrons. The excess energy is released as X-ray fluorescence. The emitted spectral lines contain characteristic features of each element, like fingerprints, and are independent of the chemical state of the atom. The intensity of the radiation is proportional to the concentration of the element in the sample.

Coal ash is the solid residue left after the high-temperature combustion of minerals in coal. Its composition is complex, mainly consisting of oxides and salts of elements such as sodium, magnesium, aluminum, silicon, phosphorus, sulfur, potassium, calcium, titanium, and iron. Coal ash composition analysis is an important aspect of coal quality testing and research.

Significance of Coal Ash Composition Analysis

u Determines the mineral composition of coal.

u Determines the melting temperature of coal.

u Provides data for the comprehensive utilization of ash residue.

u Based on the levels of oxides, it can roughly indicate the corrosion condition of boilers during coal combustion.

The A650 X-ray Fluorescence Spectrometer developed by JPSPEC Instruments meets the precision requirements for the analysis of various element oxides as specified in GB/T 37673-2019 Methods for Analysis of Coal Ash Composition. It also offers advantages such as simple sample preparation, fast analysis speed, and low analysis costs. It can also be extended to the analysis of coal gangue and coal mine element composition.
