Overview

High-precision isotope-ratio measurement.

In the MC-ICP-MS, different isotopic beams are measured simultaneously in a multicollector arrangement. This reduces the effect of signal fluctuations and favors accurate measurements of radiogenic, stable and non-traditional systems.

The choice between Neoma and Neoma MS/MS depends mainly on the nature of the interferences. Neoma combines high resolution, wide detection flexibility and high sensitivity; Neoma MS/MS adds mass selection before cell and collision/reaction chemistry to separate isobars and reduce matrix.

System Settings

Neoma or Neoma MS/MS?

Both settings share the multi-collector platform. The decisive difference is the treatment of isobaric interference before the analysis of reasons.

01High resolution multicollector

Neoma MC-ICP-MS

It combines ICP source, magnetic sector analyzer, high resolution and variable multicollector arrangement for simultaneous measurements.

Most suitable forisotope systems in which mass resolution, prior chemical separation and detector configuration solve the analytical challenge.

02Mass filter + reaction cell

Neoma MS/MS MC-ICP-MS

Add pre-cell mass filter and collision/reaction hexapolar cell before magnetic sector and simultaneous detection.

Most suitable forIsobaric interferences that cannot be separated by resolution only, such as challenges involving Rb/Sr and other complex systems.

Selects the mass of interest before the cell.
Reduces matrix input and formation of new interferers.
Allows mass displacement by controlled reactions.
Preserves simultaneous multicollector measurement after reaction.

Technology

Control of beam, interference and detection.

The family performance results from integration between source, interface, ionic optics, collectors, amplifiers and software — not a single isolated component.

Variable multicollector arrangement

Ten mobile Faraday cups and a double-mode central channel allow you to adjust geometry to the different isotope systems without sacrificing the native dispersion of the analyzer.

Wideband detection

Faraday, high-resistance amplifiers and ion counters can be combined to cover very low-intensity signals.

Jet Interface

With dessolvating nebulization, it increases the transmission of ions and favors analysis of small amounts of sample and low abundance isotopes.

MS/MS when resolution is not enough

The pre-cell filter limits what enters the cell; the reaction separates the analyte from interfering species before the final analysis in the magnetic sector.

Qtegra ISDS

Guided flows, data evaluation and peripheral integration help make advanced methods more reproducible and productive.

Frequently Asked Questions

Questions about the platform.

Technical information on the selection and configuration of the platform.

01What is the difference between Neoma and Neoma MS/MS?

Neoma is a high-resolution MC-ICP-MS with simultaneous multicollector detection. Neoma MS/MS adds a mass filter before a collision/reaction cell, allowing you to separate isobaric interferences that are not solved by mass resolution alone.

02Can Neoma be coupled to laser ablation?

Yes. The platform integrates laser ablation systems for in situ isotope analysis in heterogeneous minerals, materials and samples. The configuration depends on the element, spatial resolution and accuracy required.

03Does Neoma replace an IRMS of gases like DELTA Q?

No. Neoma measures elemental isotope ratios after plasma ionization, especially of metallic, radiogenic and non-traditional elements. DELTA Q is mainly focused on C, N, S, O and H in gases, whole samples and compounds converted into gases.

04When to choose Neoma instead of Element XR?

Choose Neoma when the priority is the maximum precision of isotope ratios by simultaneous multicollector detection. Element XR is better suited when the objective combines multielement ultratraces analysis, high resolution and large dynamic range with isotopic capacity.

05Can existing Neoma receive MS/MS technology?

Thermo Scientific presents Neoma with an update path for MS/MS. The feasibility and scope of the update shall be confirmed for the configuration and serial number of the instrument.
