Ultra Carry

With the patented Rigaku Ultra Carry, you can use your XRF 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.

Ultra Carry is a novel disposable (single-use) sample retainer for 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.
