The GeoLasPro features 193nm solid sampling from isotope ratios to fluid inclusions for unlimited LA-ICP-MS capability. Its unmatched energy and mechanical stability provides reliable sampling day after day. - Petrographic inspection of samples and ablation results
- Energy densities from <1J/cm2 to 45J/cm2
- Variable apertures for 4µm to 160µm pits
- Quadratic apertures for high fill factor rastering
- Shortest wavelength (193nm) is the most versatile with lowest intrinsic fractionation
- Highest photon energy (6.4eV) for efficient absorption in every material
- Highest depth control (0.1µm) for depth profiling with 100nm precision
- Software package for convenient sampling and system handling
