Solid sampling UV excimer system for LA-ICP-MS.
The GeoLasHD makes the most out of today’s advanced mass spectrometers. It provides unmatched energy densities for material-independent solid sampling. GeoLasHD uses sophisticated homogenizing optics to ensure accurate and shallow depth control, along with flat-bottom craters.
Using 193 nm wavelength in solid sampling produces smaller particle sizes, highest signal intensities and lowest intrinsic fractionation due to optimum material-light interaction. GeoLasHD has a rigid design which is virtually maintenance-free and allows the user to focus on what he is really interested in – uncompromised solid sampling and data recording day after day.
