A wide variety of biomass, from triglycerides to lignocellulosic-based feedstock, are among promising candidates to possibly fulfill requirements as a substitute for crude oils as primary sources of chemical energy feedstock. During the feedstock processing carried out to increase the H:C ratio of the products, heteroatom-containing compounds can promote corrosion, thus limiting and/or deactivating catalytic processes needed to transform the biomass into fuel. The use of advanced gas chromatography techniques, in particular multi-dimensional gas chromatography, both heart-cutting and comprehensive coupled to mass spectrometry, has been widely exploited in the field of petroleomics over the past 30 years and has also been successfully applied to the characterization of volatile and semi-volatile compounds during the processing of biomass feedstock. This review intends to describe advanced gas chromatography-mass spectrometry-based techniques, mainly focusing in the period 2011-early 2020. Particular emphasis has been devoted to the multi-dimensional gas chromatography-mass spectrometry techniques, for the isolation and characterization of the oxygen-containing compounds in biomass feedstock. Within this context, the most recent advances to sample preparation, derivatization, as well as gas chromatography instrumentation, mass spectrometry ionization, identification, and data handling in the biomass industry, are described.
从甘油三酯到基于木质纤维素的原料，各种各样的生物质都有望成为替代原油的主要化学能源原料，以满足需求。在进行原料加工以提高产品的 H:C 比时，含杂原子的化合物会促进腐蚀，从而限制和/或使转化生物质为燃料所需的催化过程失活。在过去的 30 年中，多维气相色谱技术，包括切割和全二维气相色谱与质谱联用，在石油组学领域得到了广泛的应用，并已成功应用于生物质原料加工过程中挥发性和半挥发性化合物的表征。本综述旨在描述基于先进气相色谱-质谱的技术，主要集中在 2011 年至 2020 年初。特别强调多维气相色谱-质谱技术，用于生物质原料中含氧化合物的分离和表征。在这方面，描述了生物质产业中样品制备、衍生化以及气相色谱仪器、质谱电离、鉴定和数据处理方面的最新进展。
