Product Name: SEIKO SEA 2210APurpose: It is an energy-dispersive X-ray fluorescence analyzer, suitable for industries such as electronics, environmental protection, and toy manufacturing, used to detect elements from aluminum (Al) to uranium (U) in materials. It can assist enterprises in detecting whether products comply with environmental regulatory substance standards such as RoHS, identifying alloy components, and conducting quality control and compliance testing.Technical Principle: Based on X-ray fluorescence (XRF) technology, the X-ray tube emits primary X-rays, which are collimated to form a fixed-diameter beam and irradiate the sample. The sample is excited to generate X-ray fluorescence, and the detector with energy resolution detects the energy of the fluorescence for elemental qualitative analysis. Quantitative analysis is completed by detecting the fluorescence intensity.Performance: It can measure elements from Al to U, and can start detecting from Na element in a vacuum environment; equipped with a high-count-rate detector for high detection sensitivity; has an automatically switched primary filter to effectively remove scattered rays from the tube target, reduce the background, and detect small peaks; for the measurement of small samples, standard curves can be used for correction; it can also correct the shape and thickness of samples through the scattered ray method to improve analysis accuracy.
