Product Name: SHIMADZU EDX-900SPurpose: Suitable for industrial material analysis, environmental monitoring and other fields. It can perform qualitative and quantitative elemental analysis on metal, ore, plastic and other samples, detect harmful substances, identify material components, and assist in quality control and compliance testing.Technical Principle: Based on X-ray fluorescence (XRF) technology, X-rays excite atoms in the sample, causing their outer electrons to transition and emit characteristic fluorescence. The instrument determines the types and contents of elements by detecting the energy and intensity of the fluorescence.Performance: The detectable element range is from sodium (Na) to uranium (U); high analysis accuracy with a relative standard deviation of ≤0.5%; equipped with a high-resolution detector with a detection limit as low as 0.1ppm; fast analysis speed, with routine sample detection time ≤60 seconds, supporting continuous testing of batch samples.
