能量色散X射线荧光光谱仪

快速定性和定量分析元素

NEX CG

理学公司的NEX CG可以通过少量的标准样品提供对各种样品的主要和次要原子元素的快速定性和定量分析测试。

用于微量水平灵敏度的解析几何光学

optical schematic

与常规 EDXRF 分析仪不同,NEX CG中设计了独特的紧密耦合解析几何光学(CG)核心,可以大大提高信噪比。通过使用二次靶材励磁代替直接励磁,使灵敏度得到了改善。由此大幅减少背景噪声同时增大元素的峰。因此即使是分析困难的样品类型也可以通过此光谱仪例行微量元素分析。

新型软件降低了对标准的需要

NEX CG配备了新型定性和定量分析软件RPF-SQX,该软件具有Rigaku Profile Fitting(RPF)的科技代表性。该软件允许标准样品以外的几乎所有样品类型的半定量分析,同时也对标准样品进行严格的定量分析。

Aqueous Liquid Sample Carrier for PPB-level Trace Element Analysis
With the patented Rigaku UltraCarry, you can use your Rigaku NEX CG spectrometer to quantify trace elements in aqueous liquids down to parts-per-billion (ppb) concentration levels. Routine elemental analysis of contaminated water or industrial wastewater can now be performed without an Atomic Absorption (AA) or Inductively Coupled Plasma (ICP) spectrometer. UltraCarry based trace element analysis is suitable for use by non-technical personnel.
  • Analyze a wide range of elements (11Na to 92U)
  • PPB-level elemental detection limits for aqueous samples
  • Simple three-step process: pipette, dry and measure
  • Easy-to-use EZ Analysis NEX CG user interface

EDXRF trace element analysis only from Rigaku
UltraCarry is a novel disposable (single-use) sample retainer for X-ray fluorescence (XRF) analysis that is used to preconcentrate a liquid sample into an uniform sample carrier that is optimized for the suppression of background noise. This approach dramatically improves the signal-to-noise ratio, resulting in almost three orders of magnitude improvement in the Lower Limit of Detection (LLD or LOD) and Limit of Quantification (LOQ) for heavy elements.
The UltraCarry sample retainer comprises a ring-shaped support fitted with a X-ray transmissive hydrophobic film and central liquid absorbent element pad. For routine analysis using UltraCarry, a recommended vacuum dryer apparatus — Rigaku UltraDry — is available as an XRF accessory.
