Compact, High Throughput SIMS for Geoscience Laboratories 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. ... 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.
