Coherent GeoLasHD Solid Sampling System

Laser ablation of solid samples at 193nm



The GeoLasPro solid sampling system for LA-ICP-MS from Coherent Inc provides unmatched energy densities ranging from below 1 J/cm2 up to 50 J/cm2 for material-independent solid sampling. GeoLasPro utilises sophisticated homogenising optics to ensure accurate and shallow depth control, along with flat-bottom craters. Using 193nm wavelength in solid sampling produces smaller particle sizes, highest signal intensities and lowest intrinsic fractionation due to optimum material-light interaction. GeoLasPro has a rigid design which is virtually maintenance-free and allows the user to focus on the work at hand.



  • Ultrashort 193nm wavelength for clea ablation in every material
  • Schwarzschild ablation objective enabling widest fluence range at superior crater bottom flatness
  • HD camera and EAGLE software package for wide area sample inspection with micro resolution
  • Multi-format sample cell with fast washout time to deliver stable and assignable ICP-MS signals
  • Sub-micron precision xyz stage and bidirectional control of mass spectrometer to provide the highest process control
