April 2018 – Extra High Resolution for MC-ICPMS

Resolve challenging interferences with the new Thermo Scientific™ XHR™ Extra High Resolution option for the Thermo Scientific™ Neptune Plus™ MC-ICP-MS.

Hydrides present the most challenging interferences to effectively resolve, and these interferences can affect high-precision isotope ratio measurements of silicon, magnesium, chlorine, and potassium, among other elements. The new XHR™ option offers a mass resolving power of over 15,000 (5, 95% edge definition) with ≥ 1% transmission and is optimized to resolve interferences introduced by hydrides and other compounds. Quantitative separation of 40Ar1H+ from 41K+ allows for the precise and accurate determination of δ41K. Other applications that are expected to benefit from this new option include high-precision Mg, Si and Cl isotope ratio measurements, where hydride interferences could otherwise affect accuracy.

When combined with the peak position and mass bias stability of the Neptune Plus multicollector inductively coupled plasma mass spectrometer (MC-ICP-MS), your isotope ratio measurements are performed accurately, precisely, and with high resolution.
