DM2300 X-ray fluorescence multi-element analyzer Introduction
DM2300 X-ray fluorescence analyzer (or X-ray fluorescence spectrometer) (English name: DM2300 EDXRF Analyzer) is the company's original DM series X-ray fluorescence calcium iron analyzer, sulfur analyzer, aluminum silicon analyzer, multi-element analyzer, etc. Based on the development of an analytical instrument that has reached the international advanced level. The instrument uses Energy Disperse X Ray Fluorescence (EDXRF) analysis technology to analyze all elements from aluminum (atomic number 13) to uranium (atomic number 92), which can be analyzed for most elements. Coating thickness measurements can also be made up to 1 ppm up to 100%. It has the characteristics of fast analysis, high precision, small human error, simple operation, only one-time investment, no pollution, so it is widely used in various industries such as electrical and electronic, building materials, metallurgy, petroleum, chemical, geological, mining. Features
(1) Using EDXRF physical analysis method, the sample does not contact or destroy the sample, and no other auxiliary materials such as chemical reagents are needed.
(2) Multi-element simultaneous rapid analysis, generally give the ppm content of Cl chlorine, chromium Cr, arsenic As, selenium Se, bromine Br, cadmium Cd, strontium Sb, strontium Ba, mercury Hg, lead Pb and other elements in a few minutes.
(3) With X-ray tube excitation, the voltage and current of the high voltage of the light pipe can be adjusted, so that the instrument can achieve the highest excitation efficiency and the best counting rate. .
(4) With 4 color filters and 4 collimators, it can be automatically converted and combined to achieve the best counting rate and the highest peak-to-back ratio, which has extremely high precision and small detection limit. .
(5) High-resolution PIN semiconductor detectors are used to effectively avoid mutual interference of elements.
(6) Using a high-resolution CCD camera, the sample platform can be moved to ensure accurate measurement of the target position.
(7) Display, operation and data processing by computer, which makes the operation simple and fast and accurate.
