应用激光诱导击穿光谱（LIBS）对新鲜蔬菜中的微量元素进行了分析。采用四倍Nd:YAG激光器进行烧蚀实验。分析的样本来自当地市场，代表了人们经常食用的蔬菜。对于典型的块根蔬菜，如马铃薯，等离子体发射的光谱分析揭示了27个元素和2个分子发射的400多条线。C-2和CN。在这些物种中。人们可以找到微量元素和超微量元素。对几种具有强辐射的微量元素进行空间分辨分析，然后应用于典型的根、茎和水果蔬菜。本研究的结果表明，这一有趣的工具有潜力用于植物和农业研究，以及食品质量/安全和环境污染评估和控制。(C) 2008 Elsevier B.V.版权所有
Laser-induced breakdown spectroscopy (LIBS) has been applied to analyze trace elements contained in fresh vegetables. A quadrupled Nd:YAG laser is used in the experiments for ablation. Analyzed samples come from local markets and represent frequently consumed vegetables. For a typical root vegetable, such as potato, spectral analysis of the plasma emission reveals more than 400 lines emitted by 27 elements and 2 molecules. C-2 and CN. Among these species. one can find trace as well as ultra-trace elements. A space-resolved analysis of several trace elements with strong emissions is then applied to typical root, stem and fruit vegetables. The results from this study demonstrate the potential of an interesting tool for botanical and agricultural studies as well for food quality/safety and environment pollution assessment and control.
