Product Name: Malvern PANalytical Epsilon 5Purpose: It can be widely applied in fields such as agriculture, food, bioengineering, new materials, environment, petrochemical products, coating thickness and composition, building materials, and archaeology. It is especially suitable for sub - ppm level analysis of medium and heavy elements and can detect samples such as solids, liquids, thin films, and powders.Technical Principle: It is an energy - dispersive X - ray fluorescence spectrometer. It adopts a 600W high - power and 100kV high - voltage three - dimensional polarized excitation source, using polarized light or a secondary target to excite the sample. The X - ray tube, polarized target or secondary target and the sample have a three - dimensional geometric layout. Through the characteristic X - ray fluorescence generated by different elements when excited, the detector receives and converts it into an electrical signal, and then analyzes the types and contents of elements.Performance: The analysis element range is from Na (11) to U (92); the X - ray tube power is 600W, and the maximum tube voltage is 100kV; up to 15 secondary targets can be installed; equipped with an ultra - large - area high - purity Ge detector with a resolution of <135eV; the count rate is as high as 200kcps; the detection limit can reach the ICP level, and the detection limit for medium and heavy elements (Fe - U) often reaches the sub - ppm level.
