提出了激光诱导击穿光谱 (LIBS) 的新仪器变体，允许使用多光谱仪和同步、多电荷耦合器件光谱采集系统同时测定所有可检测元素。该设备的设计目的是减少通常与 LIBS 应用相关的成本损失，同时允许准确和精确地确定散装材料的元素组成。该系统特别适合分析煤炭和矿石等异质材料。在煤炭分析中，除了 C 和 H 之外，可检测元素还包括煤炭的关键无机成分，例如 Al、Si、Mg、Ca、Fe、Na 和 K。检测限因特定元素而异，但对于原始潮湿材料来说，检测限通常为 0.01% 左右。测量重复性和准确度通常在±10%绝对范围内，这与异质材料的标准分析程序的结果相似。是...
A new instrumentation variation on laser induced breakdown spectroscopy (LIBS) is presented that allows simultaneous determination of all detectable elements using a multiple spectrograph and synchronous, multiple charge coupled device spectral acquisition system. The device has been designed to reduce the cost penalties often associated with the application of LIBS while allowing accurate and precise determination of the elemental composition of bulk materials. The system is particularly suited to the analysis of heterogeneous materials such as coal and mineral ores. In coal analysis detectable elements include the key inorganic components of coal—such as Al, Si, Mg, Ca, Fe, Na, and K—in addition to C and H. Detection limits vary depending on the particular element, but are typically of the order of 0.01% for as received, moist materials. Measurement repeatability and accuracy are typically within ±10% absolute, which is similar to results from standard analysis procedures for heterogeneous materials. Be...
