EDXRF & XRT

Energy dispersive X-ray fluorescence (EDXRF) is a routinely used analytical technique for the qualitative and quantitative determination of major and minor atomic elements in a wide variety of sample types. The heart of its versatility stems from the ability to provide rapid, non-destructive, multi-element analyses—from low parts-per-million (ppm) levels to high weight percent (wt%) concentrations—for elements from sodium (¹¹Na) to uranium (⁹²U).

X-ray Transmission (XRT) on-line process analyzers are routinely employed to classify crude oil and marine bunker fuels that contain 0.02-6 wt% sulfur (S). In this method, sulfur absorbs X-rays transmitted between an X-ray source and detector. The technique is well suited to the high pressures and extreme temperatures employed in transmission pipelines and blending operations.

UltraCarry®

Aqueous Liquid Sample Carrier for PPB 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

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.
