研究了激光诱导击穿光谱（LIBS）在低灰褐煤化学分析中的应用。使用Nd：YAG激光器（λ = 1064 nm）诱导来自灰形成组分的发射，然后对所述发射进行光谱解析和分析。LIBS分析的五个无机成分的褐煤被证明是可重复的样品颗粒之间在95%的置信水平。从30个褐煤样品的研究中获得了60（Ca和Al），70（Na），90（Fe）和200（Mg和Si）的接收基础上的检测限（ppm），每个样品都被300个激光脉冲询问。
The application of laser-induced breakdown spectroscopy (LIBS) to the chemical analysis of low-ash lignite has been investigated. A Nd: YAG laser (λ = 1064 nm) is used to induce emission from the ash-forming components, which is then spectrally resolved and analyzed. LIBS analyses of five inorganic components of lignite were shown to be reproducible between sample pellets at a 95% confidence level. Detection limits (in ppm) on an as-received basis of 60 (Ca and Al), 70 (Na), 90 (Fe), and 200 (Mg and Si) were obtained from a study of 30 lignite samples, each of which was interrogated by 300 laser pulses.
