Aqueous Liquid Sample Carrier for PPB-level Trace Element Analysis

Ultra Carry and NEX CG
With the patented Rigaku Ultra Carry, 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. Ultra Carry-based trace element analysis is suitable for use by non-technical personnel.

  • Analyze a wide range of elements (sodium to uranium)
  • PPB-level elemental detection limits for aqueous samples
  • Simple three-step process: pipette, dry, and analyze
  • Easy-to-use EZ Analysis NEX CG user interface

EDXRF Trace Element Analysis Only from Rigaku: US 7,016,463

Ultra Carry is a novel disposable (single-use) sample retainer for X-ray fluorescence (XRF) analysis used to preconcentrate a liquid sample into a uniform sample carrier 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 Ultra Carry sample retainer comprises a ring-shaped support fitted with an X-ray transmissive hydrophobic film and a central liquid absorbent element pad. For routine analysis using Ultra Carry, a recommended vacuum dryer apparatus—Rigaku UltraDry—is available as an XRF accessory.
