Overview
The DM2500 MMEDXRF Light-to-Medium Element Spectrometer—specifically the DM2500 Multi-Monochromatic Excitation Energy Dispersive X-Ray Fluorescence Spectrometer for light-to-medium elements (B–Zn)—is an innovative XRF spectrometer developed by the company. It builds upon decades of research experience and the foundation of the company's existing DM series analyzers (including XRF sulfur/calcium/iron analyzers, multi-element analyzers, and general XRF spectrometers). It utilizes Multi-Monochromatic Excitation Energy Dispersive X-Ray Fluorescence (MMEDXRF) analysis technology. Key components include: a proprietary logarithmic spiral, rotating point-to-point focusing germanium monochromator crystal developed in-house; a 50W micro-focus, wide-emission-angle, thin-beryllium-window X-ray tube from KeyWay (with optimized high-voltage, current, and target material settings); and a room-temperature SDD semiconductor X-ray detector from Ketek (Germany) featuring high count rates, high energy resolution, and high transmission. Furthermore, the instrument incorporates unique technologies—such as an optical system specifically designed for light elements and a multi-monochromatic excitation system utilizing a combination of methods—which significantly enhance sensitivity and the peak-to-background ratio. It utilizes a downward-irradiation X-ray system and a sample rotation mechanism—making it particularly well-suited for pressed powder samples—and offers a choice between vacuum and gas-purged systems depending on the application. These features place the spectrometer at the forefront of international technology. Comparative tests against large-scale wavelength-dispersive spectrometers show that most of its performance metrics match or approach those of the larger instruments, with some even surpassing them. It outperforms similar imported products while costing only half as much, offering an unrivaled price-to-performance ratio. Furthermore, the convenience of after-sales service provided by a domestic manufacturer is unmatched by foreign competitors. Additionally, the spectrometer’s robust shielding design ensures zero radiation leakage, meeting requirements for radiation safety exemption.
Applications
The DM2500 MEDXRF spectrometer for light and medium elements is suitable for measuring elemental content across a wide range of industries and materials. Whether in sectors such as environmental protection, metallurgy, chemicals, geology, mining, electronics, or food processing—and for sample types including pressed pellets, fused beads, or liquids—the DM2500 delivers accurate measurements for any elements within the B(5) to Zn(30) range. It complies with the requirements of virtually all standards for elemental determination via XRF spectrometry, such as national or industry standards: GB/T 176—2017 *Methods for Chemical Analysis of Cement*; GB/T 3286.11-2022 *Methods for Chemical Analysis of Limestone and Dolomite – Part 11: Determination of Calcium Oxide, Magnesium Oxide, Silicon Dioxide, Aluminum Oxide, and Iron Oxide Contents – Wavelength Dispersive X-ray Fluorescence Spectrometry (Fused Bead Method)*; GB/T 4333.5-2016 *Ferrosilicon – Determination of Silicon, Manganese, Aluminum, Calcium, Chromium, and Iron Contents – Wavelength Dispersive X-ray Fluorescence Spectrometry (Fused Bead Method)*; YS/T 63.16—2019 *Test Methods for Carbon Materials Used in Aluminum Production – Part 16: Determination of Elemental Content – Wavelength Dispersive X-ray Fluorescence Spectrometry*; and GB/T 24198-2009 *Ferronickel – Determination of Nickel, Silicon, Phosphorus, Manganese, Cobalt, Chromium, and Copper Contents – Wavelength Dispersive X-ray Fluorescence Spectrometry (Routine Method)*. It also meets industry standards JC/T 1085—2008 *X-ray Fluorescence Analyzer for Cement* and JB/T 11145—2011 *X-ray Fluorescence Spectrometer*.
Should users have specific requirements regarding the measurement of certain elements, the company can modify the monochromatic excitation system and/or software system to meet those specific needs.
Characteristics
Rapid Simultaneous Analysis – Target elements are analyzed simultaneously and rapidly, with content results typically available within tens of seconds.
High Accuracy – Utilizes advanced MMEDXRF technology and LSDCC core technology. By selecting the optimal monochromatic energy and generation method based on the target elements, the instrument achieves significantly enhanced sensitivity and peak-to-background ratios, delivering excellent repeatability, reproducibility, and superior accuracy.
Downward Irradiation – Employs a downward X-ray irradiation system that eliminates the risk of sample powder contaminating or damaging the detection system, making it particularly suitable for pressed powder samples. Sample Rotation – Equipped with a sample rotation mechanism, it eliminates sample inhomogeneity caused by the presence of extremely hard materials that are difficult to pulverize during pellet preparation.
Long-term Stability – Utilizes a variable-gain digital multichannel analyzer (MCA) with features such as automatic PHA adjustment, drift correction, and bias compensation, ensuring excellent long-term stability.
Eco-friendly and Energy-efficient – Radiation protection meets exemption standards. The analysis process is non-contact and non-destructive; it generates no pollution and requires no chemical reagents or combustion.
Ease of Use – Touch-screen operation. After placing the pulverized and pressed sample into the instrument, simply press the [Start] button to initiate the process—achieving true one-touch operation.
High Reliability – Features an integrated design with a high level of component integration, strong environmental adaptability, robust interference resistance, and high reliability.
High Cost-effectiveness – Requires no gas cylinders, resulting in extremely low operating and maintenance costs. Priced at half that of comparable foreign products, it offers exceptional value for money.
