Laser Ablation of Solid Samples at 193 nm
GeoLasHD is the next generation laser ablation system for all-encompassing LA-ICP-MS elemental and isotopic analysis. Powered by the powerful 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 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.
