Lignin is the second most abundant natural biopolymer, which is a potential alternative to conventional fossil fuels. It is also a promising material for the recovery of valuable chemicals such as aromatic compounds as well as an important biomarker for terrestrial organic matter. Lignin is currently produced in large quantities as a by-product of chemical pulping and cellulosic ethanol processes. Consequently, analytical methods are required to assess the content of valuable chemicals contained in these complex lignin wastes. This review is devoted to the application of mass spectrometry, including data analysis strategies, for the elemental and structural elucidation of lignin products. We describe and critically evaluate how these methods have contributed to progress and trends in the utilization of lignin in chemical synthesis, materials, energy, and geochemistry.
木质素是第二丰富的天然生物聚合物，是传统化石燃料的潜在替代品。它也是回收有价值化学品（如芳香族化合物）的有前途的材料，也是陆地有机质的重要生物标志物。木质素目前作为化学制浆和纤维素乙醇工艺的副产品大量生产。因此，需要分析方法来评估这些复杂木质素废物中所含的有价值化学品的含量。本综述致力于介绍和评价质谱在木质素产品的元素和结构解析方面的应用，包括数据分析策略。我们描述并批判性地评价了这些方法如何促进了木质素在化学合成、材料、能源和地球化学中的利用的进展和趋势。
