There has been a large increase in the number of papers published that are relevant to this review over this review period. The growth in popularity of LIBS is rapid, with applications being published for most sample types. This is undoubtedly because of its capability to analyse in situ on a production line (hence saving time and money) and its minimally destructive nature meaning that both forensic and cultural heritage samples may be analysed. It also has a standoff analysis capability meaning that hazardous materials, e.g. explosives or nuclear materials, may be analysed from a safe distance. The use of mathematical algorithms in conjunction with LIBS to enable improved accuracy has proved a popular area of research. This is especially true for ferrous and non-ferrous samples. Similarly, chemometric techniques have been used with LIBS to aid in the sorting of polymers and other materials. An increase in the number of papers in the subject area of alternative fuels was noted. This was at the expense of papers describing methods for the analysis of crude oils. For nanomaterials, previous years have seen a huge number of single particle and field flow fractionation characterisations. Although several such papers are still being published, the focus seems to be switching to applications of the nanoparticles and the mechanistic aspects of how they retain or bind with other analytes. This is the latest review covering the topic of advances in the analysis of metals, chemicals and materials. It follows on from last year’s review and is part of the Atomic Spectrometry Updates series.

原子光谱法更新：审查金属，化学物质和材料的分析进展

在此审查期间，与该审查相关的已发表论文的数量已大大增加。LIBS的普及度迅速增长，其中针对大多数样本类型发布了应用程序。毫无疑问，这是因为它具有在生产线上进行原位分析的能力（因此节省了时间和金钱），并且具有极小的破坏性，这意味着可以分析法医和文化遗产样本。它还具有隔离分析功能，这意味着危险材料，例如可以从安全距离分析炸药或核材料。数学算法与LIBS结合使用以提高准确性已被证明是一个受欢迎的研究领域。对于黑色金属和有色金属样品尤其如此。类似地，化学计量学技术已与LIBS一起使用，以帮助对聚合物和其他材料进行分类。注意到替代燃料这一主题领域的论文数量有所增加。这是以描述原油分析方法的论文为代价的。对于纳米材料，前几年已经看到了大量的单颗粒和场流分级表征。尽管仍在发表几篇此类论文，焦点似乎转移到了纳米颗粒的应用以及它们如何保留或与其他分析物结合的机理方面。这是最新的评论，内容涉及金属，化学物质和材料分析的最新进展。它是从去年的审查之后得出的，它是“原子光谱更新”系列的一部分。
