日本理学 RIGAKU Supermini 200用途：可对固体、液体、粉末、合金和薄膜等几乎任何材料，进行氧（O）至铀（U）的元素分析，适用于材料分析、矿石检测、工业质量控制等领域。技术原理：属于波长色散型 X 射线荧光（WDXRF）光谱仪。利用 X 射线照射样品，使样品中的原子内层电子被激发，外层电子跃迁填补空位，产生特征 X 射线荧光。通过晶体将不同波长的荧光 X 射线分开，进而确定元素种类和含量。性能：配备 200W 高功率空冷 X 射线管，提升灵敏度；拥有高分辨率，能有效分辨复杂基质中的谱线重叠；可分析轻元素，如 F、Na 等；带有三位置晶体变换器，标配 LiF (200) 和 PET 晶体，可选配 RX25 或 Ge 晶体；支持真空或氦气环境测量；样品尺寸可容纳直径 51.5 毫米的样品，还可选 12 位自动进样器 。

Product Name: Rigaku Supermini 200Purpose: It can perform elemental analysis of oxygen (O) to uranium (U) in almost any materials such as solids, liquids, powders, alloys and thin films. It is suitable for fields like materials analysis, ore detection and industrial quality control.Technical Principle: It belongs to the wavelength dispersive X - ray fluorescence (WDXRF) spectrometer. When the sample is irradiated with X - rays, the inner - layer electrons of atoms in the sample are excited, and the outer - layer electrons transition to fill the vacancies, generating characteristic X - ray fluorescence. Crystals are used to separate fluorescent X - rays of different wavelengths, thus determining the types and contents of elements.Performance: Equipped with a 200W high - power air - cooled X - ray tube to improve sensitivity; has high resolution to effectively resolve spectral line overlaps in complex matrices; can analyze light elements such as F, Na, etc.; equipped with a three - position crystal changer, with LiF (200) and PET crystals as standard, and optional RX25 or Ge crystals; supports measurement in vacuum or helium environment; the sample size can accommodate samples with a diameter of 51.5 mm, and a 12 - position autosampler is also optional.
