Overview
Interference separation in complex matrices.
The Element Series uses a dual-focused magnetic sector analyzer and selectable cracks to physically separate ions from the analyte from interfering species species. This reduces reactive gas dependence and allows working with a multi-element method even in complex matrices.
Element 2 and Element XR share the same proposal of high resolution, sensitivity and stability. The XR adds Faraday detector and extends the dynamic range in three orders of magnitude, being especially valuable when major and ultratrace signals need to be measured in the same flow.
01multi-element concentration of majority ultratrace levels.
02Accurate isotope ratios, including among isotopes of very different abundances.
03transient signals of laser ablation, chromatography and individual particles.
05Analytes affected by doubly charged oxides, argon-based species, nitrides or ions.
System Settings
Element 2 or Element XR?
Both models use magnetic sector HR-ICP-MS. The choice depends mainly on the dynamic range and detection system required by the application.
01Double mode detection
Element 2 HR-ICP-MS
Robust solution for chemical analysis, semiconductors, research and production control with high sensitivity and physical resolution of interference.
Most suitable formultielement and isotopic methods in which the dynamic range of up to 109 cps meets the present concentrations.
SEM detector with two-way operation.
Linear range of less than 0,2 cps to more than 109 cps.
Three fixed resolutions in exchange in less than a second.
High sensitivity in wet and dry plasma with Jet Interface.
02SEM + Faraday
Element XR HR-ICP-MS
It adds Faraday detection and expands the dynamic range to deal with very intense signals, large isotope ratios and poorly known composition samples.
Most suitable forFull screening, laser ablation, matrices with large concentration variation and ratios between major and minority isotopes.
Dynamic range extended to more than 1012 cps.
Three additional magnitude orders against Element 2.
Additional filter for better sensitivity of abundance.
Automatic switch to Faraday when the signal exceeds the SEM range.
Technology
High resolution with magnetic sector.
The family combines physical separation in the magnetic sector, high sensitivity and wide detection range for transient solutions and signals.
Element XR presented in the official catalogue of the Element Series family.
01
Three resolution modes
LR R=300 maximizes sensitivity; MR R=4,000 solves most interferences; HR R=10,000 separates spectral challenges into complex matrices.
02
Separation without reactive chemistry
Analyte is physically separated from interferents such as oxides, argon-based species, nitrides and doubly charged ions, preserving a direct multielement flow.
03
Integrated Jet Interface
Cones and high-capacity pumping increase the transmission of ions in wet and dry plasma, favoring detection limits and transient signals.
04
Detection according to intensity
Element 2 uses SEM in double mode. The Element XR combines SEM and Faraday to cover more than twelve orders of magnitude.
05
Stability for isotope ratios
Mass and signal stability support accurate isotopic measurements and long series, both in solution and in situ analysis.

Technical information on the selection and configuration of the platform.
01What is the difference between Element 2 and Element XR?+
The two offer HR-ICP-MS magnetic sector with resolutions R=300, 4,000 and 10,000. The Element XR adds Faraday detector and extends the dynamic range in three orders of magnitude, from more than 109 cps in Element 2 to more than 1012 cps.
02Does the Element Series measure isotope ratios?+
Yes. High sensitivity, stability and physical resolution allow accurate isotope ratios. However, when priority is maximum accuracy by simultaneous detection of multiple isotopes, a multi-collector platform such as Neoma may be more appropriate.
03How does Element remove interference?+
The magnetic sector analyzer uses high mass resolution to physically separate peaks from analytes and interferers. Thus, many interferences can be resolved without depending on collision or reaction gases.
04Can Element work with laser ablation?+
Yes. The series is suitable for transient signals of laser ablation and is used in in situ analyses, including elemental quantification and U-Pb dating in minerals.
05When is Element XR preferable to Element 2?+
XR is preferable when the same analysis involves very intense and ultratrace signals, large isotope ratios, poorly known concentration matrices or laser ablation with wide signal variation.
