Mass spectrometer: ICP-MS
Finnigan ELEMENT 2
The unequivocal separation of analyte ions from spectral interferences is a prerequisite of accurate and precise elemental analysis. High mass resolution is the universal means for this separation. The capability of high mass resolution is a feature unique to the Finnigan ELEMENT2: it is the only high performance, double focusing magnetic sector field ICP-MS.
Everything in Everything (almost)
The Finnigan ELEMENT 2 is a double focusing magnetic sector field ICP-MS.
- Interference free measurement of almost the whole periodic table and in almost all matrices
- From ultra-trace to matrix components
- Quantitative, Isotopic and Species Information
ICP-MS is the accepted and most powerful technique for the analysis and quantification of trace elements. Its applications range from the semiconductor industry to geological and environmental analyses, from biological research to material sciences. The most severe limitation of ICP-MS are polyatomic interferences on the elemental signals, originating from Argon and/or the sample matrix. High Mass resolution is the Gold Standard for the identification and elimination of interferences. Elimination of interferences enables accurate and reliable quantitative multi-element analyses at trace levels, even without sample preparation.
The ELEMENT 2 redefines high resolution ICP-MS by setting a new standard for productivity at the highest level of analytical performance. With the experience of more than 250 installed ELEMENTs, Thermo Scientific (Bremen), the leader in high resolution ICP-MS, has rigorously optimized the ELEMENT2 for ease-of-use, stability and productivity. Autotuning of all parameters, including lenses, gas flows and the torch position ensures a reproducible and reliable system setup. Refined ion optics deliver high transmission at high resolution. The Thermo Scientific (Bremen) Finnigan ELEMENT2 is the high resolution ICP-MS for routine productivity in your laboratory.
With the ELEMENT 2 there is always access to the most powerful technique to solve a specific problem, combined with the highest sensitivity and the best signal-to-noise ratio. If there is a solution using ICP-MS, the ELEMENT2 has it. No other ICP-MS system can make this claim: ultimate sensitivity at all resolution settings, ultimate selectivity through high mass resolution, 'hot' and 'cold' plasma conditions, high speed for transient signals, high stability for isotope ratios, full automation for routine productivity and full access to all instrumental parameters for method development.

The Finnigan ELEMENT 2 and the Finnigan ELEMENT XR can be used as element-specific detectors for speciation analysis when coupled to a chromatographic separation technique like HPLC, CE or GC. Not only metals, but also elements like P, S, F, Cl, Br and I can be detected quasi-simultaneously within each scan.
- Fully automated tuning and analysis
- In conjunction with a comprehensive, customizable quality control system
- Reliability and robustness to serve as a 24/7 production control tool
- Highest sample throughput
- Highest flexibility and accessibility to serve as an advanced research tool
Due to the high accelerating voltage of 8000V and excellent focusing properties, the Finnigan ELEMENT 2 and the Finnigan ELEMENT XR possess sensitivities of > 106 cps/ppb 115In, leading to extremely low limits of detection. Therefore, even low abundant elemental species can be detected.
By using Medium (R=4000) or High Mass Resolution (R=10000), the analyte ions can be completely resolved from polyatomic interferences caused by the mobile phase and/or the sample matrix. This leads to high specificity, low backgrounds and avoids possible misidentification of species not containing the elements of interest.
Fast magnetic scanning and even faster scanning of the electrical field lead to duty cycles (measurement times / measurement times + settling times) of > 90% for full mass range analysis (multi-element speciation with many elements) or > 99.9 % when the elements of interest are within a mass range of 30%. This fast scanning is important for chromatography with many data points per time interval.
The linear dynamic range of > 109 (Finnigan ELEMENT2) resp. >1012 (Finnigan ELEMENT XR) enables accurate detection of low and high abundant elemental species.
