Both the ICP-MS and MC-ICP-MS systems at the AAC can utilize the GeoLas 200 Excimer Laser Ablation System.
Using a short wavelength (193nm) laser, a wide range of solid material types can be sampled using spot sizes from 160 to 5 microns. The ablated material can be introduced directly to either the ICP-MS or MC-ICP-MS allowing for in-situ elemental or isotopic micro-analysis. Thus, rather than analysing "bulk" sample compositions, small areas (such as individual mineral grains) can be analysed directly from the solid material.
