Thermo Scientific Neoma MS/MS MC-ICP-MS

Separate out isobaric interferences to achieve new levels of precision and accuracy in your isotope research. There are some situations when even the highest resolution is not enough and isobaric interferences cannot be resolved, even with the best ICP-MS instruments available. Thermo Scientific™ Neoma™ MS/MS MC-ICP-MS provides the solution.

The Neoma MS/MS MC-ICP-MS is the first dedicated collision/reaction cell MC-ICP-MS with unique pre-cell mass filtering technology, allowing you to separate out isobaric interferences and opening up new avenues in the field of laser ablation MC-ICP-MS and beyond.

Modes

• Full transmission mode: High-precision isotope analysis without utilizing the collision/reaction cell technology. Additionally, the pre-cell mass filter can be used to remove matrix elements, boosting sensitivity and improving abundance sensitivity.
• Collision/reaction cell mode: For isotope systems with significant isobaric interferences, patented pre-cell mass filter technology removes matrix elements that might act to cause secondary reactions in the CRC.

Applications

• In-situ Rb-Sr dating: Unprecedented precision for dating geological samples by a combination of the pre-cell mass filter, the collision/reaction cell and the multicollector detector array.
• Interference-free Ti isotope analysis: The pre-cell mass filter can be used to remove molecular and doubly charged interferences, and the collision/reaction cell can be used to remove isobaric interferences.
• In-situ boron isotope analysis of biogenic carbonates: Unprecedented accuracy LA-MC-ICP-MS analysis by using the pre-cell mass filter to remove interferences from scattered Ca⁴⁺ ions on ¹⁰B
• K isotope analysis: Interference of ⁴⁰Ar⁺ can hamper the precision and accuracy of the K isotope analysis. Remove the ⁴⁰Ar⁺ interference with either: (1) the eXtra High Resolution (XHR) of Neoma MC-ICP-MS, or (2) for smaller sample sizes, the use of H₂ and He in the collision/reaction cell to neutralize ⁴⁰Ar and ⁴⁰ArH

Technology options

• Extended choice with 24 amplifier array: Ion current amplifiers are mounted in a doubly shielded, evacuated and thermostatted housing with a temperature stability of 0.01°C/hour, to guarantee baseline and gain stability.
• Enhanced variable detector array: Precise alignment of all 11 cups with ion beams of different dispersions to ensure the flexibility to cover isotopic applications from Li through to U, in low or high resolution, and without compromising the native dispersion of the mass analyzer.
• Jet Interface: The Jet Interface, in combination with a desolvating nebulizer system, increases sensitivity by 10 to 20 times compared to standard wet plasma.
• Choice of resolution: 3 different mass resolutions for maximizing the sensitivity of your analysis whilst allowing interferences to be resolved.
• Flexibility of detector types: A flexible, three-detector system spanning >9 orders of magnitude in signal intensity range (1 cps – 6 Gcps). The central channel is equipped with a dual-mode detector that can be switched from Faraday cup to SEM ion counter, and with the proprietary relay matrix, any amplifier can be assigned to any of the Faraday cups via software.
• 10¹³Ω amplifier technology: Ensures fast response times with extremely low noise characteristics. The benefits of Faraday cups can be realized at low signal intensities (30 kcps – 3 Mcps), delivering external precisions that approach the ultimate limits of counting statistics.
