CAMECA IMS 1300-HR³
Large Geometry SIMS for Geosciences
The CAMECA IMS 1300-HR³ is a large geometry ion microprobe for a wide range of geoscience applications:
- Track geological processes using stable isotopes
- Date minerals (geochronology)
- Trace element detection / distribution
- Nuclear safeguarding: locate and measure uranium particles
HR³ stands for:
- High Reproducibility
- High spatial Resolution
- High mass Resolution
This combination is ideal for small scale, high precision, in-situ isotopic measurements.

Stable Isotopes: Carbon
Map minerals and detect even minor variations in isotopic ratios, such as this diamond.
Comparing the CL image and carbon isotope map suggests that the δ13C values of natural diamonds are directly related to the δ13C composition of the mantle fluid reservoir where they grow.
Perform in-situ dating with high precision. The IMS 1300-HR³ has outstanding ion image capability for Pb and U mapping in zircon grains (inhomogeneity, zonation).
This example shows U-Pb direct dating of iron oxide-copper-gold (IOCG) mineralisation, on hydrothermal zircon crystals from IOCG-type ore deposits.
Both young and old zircon can be dated with large geometry SIMS, as well as monazite, apatite, titanite, rutile and baddeleyite for a whole range of geochronological applications.

High precision Uranium isotopic analysis on nuclear particles. SIMS is the only analytical technique that can perform in situ elemental and isotopic analysis with sub-µm spatial resolution and high sensitivity. Results can be obtained from a specimen as small as a few picograms.
This example is from a sample containing standard µm-sized U particles with dual isotopic composition.
