马尔文 PANALYTICAL XRF用途：作为 X 射线荧光光谱仪系列，适用于地质、冶金、环境、材料等领域的元素分析，可对固体、液体、粉末等样品中从钠（Na）到铀（U）的元素进行定性和定量分析，满足科研与工业质量控制需求。技术原理：X 射线管发射 X 射线激发样品，使元素产生特征 X 射线荧光，通过分光系统分离不同波长的荧光，探测器接收信号后，依据信号波长和强度确定元素种类与含量。性能：部分型号如 Epsilon 5，配备 600W X 射线管，最高管压 100kV，分析元素范围 Na-U，检出限达亚 ppm 级；PW 系列采用高分辨率晶体，多元素同时分析，计数率高达 200kcps，支持自动样品处理。

Product Name: Malvern PANalytical XRFPurpose: As a series of X-ray fluorescence spectrometers, it is suitable for elemental analysis in geology, metallurgy, environment, materials and other fields. It can perform qualitative and quantitative analysis of elements from sodium (Na) to uranium (U) in solid, liquid, powder and other samples, meeting the needs of scientific research and industrial quality control.Technical Principle: The X-ray tube emits X-rays to excite the sample, causing elements to generate characteristic X-ray fluorescence. The spectroscopic system separates fluorescence of different wavelengths. After the detector receives the signal, the types and contents of elements are determined according to the signal wavelength and intensity.Performance: Some models such as Epsilon 5 are equipped with a 600W X-ray tube with a maximum tube voltage of 100kV, covering elements from Na to U with a detection limit of sub-ppm level; PW series adopt high-resolution crystals, enabling simultaneous multi-element analysis with a count rate up to 200kcps and supporting automatic sample processing.
