激光诱导击穿光谱(LIBS)具有无需样品准备、多元素同时检测、测量速度快、可远程非接触测量等诸多优点,在原位、在线检测尤其具有优势,因此被称为化学分析技术的“未来之星”。
近年来,LIBS技术发展迅速,吸引了大量学者和工业界人士的关注,但受其定量化水平制约,尚未能实现大规模商业化。希望国内LIBS研究团队能携手共进,进行该方向的机理及应用研究、提高LIBS的定量化水平,真正推动LIBS技术发展,让LIBS成为真正的化学分析巨星,为我国的工业生产做出重大的贡献。

简介:The self-absorption effect due to optically thick property greatly influences the measured line intensities as well as the performance of quantification for laser-induced breakdown spectroscopy (LIBS) especially for calibration-free LIBS which requires proper correction. In this paper, a new self-absorption correction method for Calibration-Free LIBS (CF-LIBS), called blackbody radiation referenced self-absorption correction (BRR-SAC) is proposed. An iterative algorithm was designed to calculate the plasma temperature and normally hard-to-obtain collection efficiency of the optical collection system by directly comparing the measured spectrum with the corresponding theoretical blackbody radiation for self-absorption correction......
随着技术的发展,会有所改善的。
尼通新出的阿波罗可以检测C碳含量,RSD好像在10%左右。
学习一下
看来研发和提高LIBS的任务还很艰巨,任重道远,期待能有更好的未来。
非常期待中国在LIBS领域的发展。
