Superior Solid Sampling at 193 nm
GeoLasHD is the next generation laser ablation system for all-encompassing LA-ICP-MS elemental and isotopic analysis. Powered by the mighty COMPex laser, it uniquely combines sturdy high-resolution optical design, expert polarizer microscope, and the latest HD camera technology. The new and intuitive EAGLE control software features real-time HD monitoring of micron-size features and seamless sample mapping with an optional external image overlay.
Using 193 nm in solid sampling produces smaller particle sizes, highest signal intensities, and lowest intrinsic fractionation due to optimum material-light interaction. GeoLasHD has a sturdy design which is virtually maintenance-free and allows the user to focus on what matters the most – uncompromised solid sampling and data recording day after day.
