A unique detection system for high isotope ratio reproducibility
Derived from our proven IMS 7f instrument, the IMS 7f-GEO is equipped with a new, unique detection system combining a double Faraday cup detector system and an Electron Multiplier. Thanks to this configuration, acquisition time is shortened, and analyses are run in a pseudo bi-collection mode ensuring sub-permil precision for stable isotope ratio measurements. The double Faraday cup system is combined with a fast mass peak switching system (as fast as 0.3 sec at high mass resolving power) for further benefits in terms of precision and analysis throughput.

... And greatly improved analysis throughput
The IMS 7f-GEO achieves a major improvement in analysis throughput thanks to the implementation of the double Faraday cup detector system as demonstrated in the  above example (top right, ¹⁸O/¹⁶O isotope ratio analysis in synthetic quartz).
For a required statistical precision better than 0.4 permil, measurement time could be >3000 sec. while it falls down to 56 sec using the IMS 7f-GEO pseudo bi-collection mode.

Rare Earth Element analyses (SIMS)

The IMS 7f-GEO can deal with several molecular interferences of extremely close masses in order to measure Rare Earth Elements at trace levels.
