Multi-ion Counting Packages (MIC)

The smallest sample amounts and the lowest abundance isotopes require the use of ion counting detectors.

Both the Thermo Scientific Neoma MC-ICP-MS and Thermo Scientific Triton XT TIMS can be fitted with a Multi Ion Counting (MIC) arrays to allow simultaneous detection of the lowest abundance ion beams. Efficiency is significantly increased when compared with single collector measurements. The MIC packages offer comprehensive coverage of isotopic measurements, with flexibility to use combinations of ion counters and Faraday cups for sample amounts from the fg to μg level.

MIC for Neoma MC-ICP-MS:

Up to eleven discrete dynode secondary electron multipliers can be installed on the Neoma MC-ICP-MS, with packages tailored for different applications. The SEM and CDD ion counters available for the Neoma MC-ICP-MS offer the lowest noise with excellent stability, linearity and lifetime characteristics.

The latest extended dispersion optics available for the Neoma MC-ICP-MS allow more applications to be measured with a single MIC array than ever before. A triple-application multi-ion-counting package brings Re/Os, U/Th, and U/Pb measurements together in a single MC-ICP-MS for the first time.

MIC for Triton TIMS:

Up to eight discrete dynode secondary electron multipliers can be installed on the Triton XT TIMS, with packages tailored for different applications. The SEM and CDD ion counters available for the Triton XT TIMS offer excellent stability, linearity, and lifetime.
