Laser ablation ICP-MS allows for spatial elemental mapping and quantification down to 1 micron resolution in both biological and inorganic solid samples. The Excite delivers finely controlled, “homogenizer-flat” ablations with high sensitivity and split second response. Fire-on-the-fly lasing that is synchronized to the stage motion, combined with fast washout ablation cells, make precision depth profiling of spots, lines and areas possible and enables high spatial resolution elemental mapping. The laser is coupled to a Thermo iCapTQ, where the triple quad technology allows for greater control over isobaric interferences, reaching sub-ppt sensitivities.
