Laser Ablation ICP-MS
Laser ablation is a solid sample introduction device which uses a laser beam to vaporize and ablate a solid sample. The material injected into the laser ablation chamber is swept into the ICP-MS for elemental and isotopic analyses. The advantages are spatially resolved data down to a few microns in diameter, the ability to do depth profiling, lower potential for contamination, and speed of analysis (little or no sample preparation is required). The disadvantages are typically higher detection limits and the lack of matrix matched standards which can hinder accuracy. In our lab we feature the UP-213 from New Wave. Details of this unit are available via the brochure link on this page.
