DM2400 Monochrome Excitation Energy Dispersion X-ray Fluorescence Light Element Spectrometer Introduction
DM2400 monochromatic excitation energy dispersive X-ray fluorescence light element (Si, P, S, Cl) spectrometer, referred to as DM2400 MEDXRF light element spectrometer, is the company's research experience for decades of X-ray fluorescence spectrometer, in the company's original Based on DM series X-ray fluorescence analyzer, X-ray fluorescence multi-element analyzer, wavelength-dispersive X-ray fluorescence multi-channel spectrometer, etc., an XRF spectrometer that has reached the international advanced level has been developed. It uses the following technologies and devices to make the DM2400 with 50W light pipe excellent reproducibility and stability, and ultra-low detection limit, which has brought the modern technology to the extreme. Features
Fast simultaneous – the required measurement elements are quickly analyzed at the same time, generally giving results in tens of seconds.
Low detection limit – using advanced MEDXRF technology, LSDCC core technology, to achieve ultra-low detection limits. Extremely reproducible and reproducible.
Long-term stability – Variable gain digital multi-channel with PHA auto-tuning, drift correction, and offset correction for excellent long-term stability.
Environmental protection and energy saving – radiation protection is up to the exemption requirement. No contact with the sample during the analysis, no pollution, no chemical reagents, no burning.
Easy to use – touch screen operation. The sample is directly loaded into the sample cup. After putting the instrument into the instrument, just press the [Start] button to realize one-button operation.
High reliability – integrated design, high degree of integration, strong environmental adaptability, strong anti-interference ability and high reliability.
Cost-effective – no cylinder gas required, low operating and maintenance costs. The price is half of the foreign similar products. It is a truly cost-effective product. Technical Parameters

Note: If the user believes that the standard DM2400 cannot meet the requirements, it can be submitted to the company, and the company can satisfy the user's requirements as much as possible. If a lower detection limit is required, the company can increase the crystal from one block to three to reduce the detection limit to 1/1.73. If you want to measure the elements of the atomic number below F, the company can select the SDD of the AP3.3 incident window for the user. If the user wants to measure trace amounts of Al and Si under the substrate of high S, the company can change the standard type of Ag target to Mo target to meet user requirements.
