Product Name: SHIMADZU EDX-720Purpose: Suitable for electronics, jewelry, environmental and other fields, used for qualitative and quantitative elemental analysis of materials. It can detect harmful element content and identify alloy components, aiding product compliance testing and quality control.Technical Principle: Based on X-ray fluorescence (XRF) technology, X-rays excite atoms in the sample, causing inner 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); equipped with a high-resolution Si-PIN detector with a detection limit as low as 1ppm; fast analysis speed, with single detection time adjustable from 30 seconds to 5 minutes; with automatic calibration function, good stability, and relative standard deviation ≤1%.
