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: US 7,016,463 

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.
