High Sensitivity Sample Introduction System

Elemental Scientific’s new apex Ω desolvating nebulizer is the highest performing ICPMS sample introduction system available. An innovative multistage Peltier-cooled desolvation system combined in series with a helical EPTFE fluoropolymer membrane desolvator gives maximum ICPMS signal while simultaneously reading the lowest ratios of oxide and polyatomic ion interferences.

  • Up to 10x-20x sensitivity increase
  • 0.01% CeO+/Ce+ ratio
  • Integrated software control of sweep gas and nitrogen flows
  • Software control of spray chamber and desolvator temperatures
  • Rapid and complete wash-out

Nd Isotope

Minimizing the amount of Nd required to obtain desired precision (> 50 ppm) and throughput for precious oceanographic samples is illustrated in two figures. First, internal precision is for plotted for variable amounts of Nd injected at 100 µL/min for two minutes. Less than 50 ppm (2 RSD) internal precision is obtained for 2 ng samples of Nd. Repeat analysis of reference materials JNdi and La Jolla indicate that the external precision for 2 ng of Nd is similar to the 50 ppm internal precision and appropriate for oceanographic applications.
