A tunable, line-narrowed ArF excimer laser was used in combination with Nd:YAG ablation for LA-LEAF (LA-LIF) determination of As in steel and dried seaweed. Relative to previous work with a standard ArF, the line-narrowing had minimal effect on the selectivity in steel plasmas. Excitation scanning did show that both the signal and limiting background result from a standard fluorescence mechanism. Preliminary work in seaweed found a detection limit of 1.0 ppm and indicated that more laser energy and further narrowing would improve detection limits slightly. Limiting background in seaweed was ArF-derived.

窄线氟化氩LA-LEAF用于痕量砷分析

可调线窄ArF受激准分子激光与Nd：YAG烧蚀结合使用，用于LA-LEAF（LA-LIF）测定钢和干燥海藻中的As。相对于以前使用标准ArF进行的研究，线变窄对钢等离子体的选择性影响很小。激发扫描确实显示信号和限制性背景均来自标准荧光机制。在海藻中进行的初步工作发现检出限为1.0 ppm，并表明更多的激光能量和进一步缩小范围会稍微改善检出限。海藻的限制背景是ArF衍生的。
