Details
The IMS 7f-GEO is a mono-collection SIMS model specifically designed to perform high precision / high throughput measurements in geological samples, i.e. stable isotopes, REE (Rare Earth Elements), trace elements… It is also used for material sciences analyses and environmental studies.
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.
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.
