Owing to the increasing environmental and climate changes globally, there is an increasing interest in the molecular-level understanding of environmental organic compound mixtures, that is, the pursuit of complete and detailed knowledge of the chemical compositions and related chemical reactions. Environmental organic molecule mixtures, including those in air, soil, rivers, and oceans, have extremely complex and heterogeneous chemical compositions. For their analyses, ultrahigh-resolution and sub-ppb level mass accuracy, achievable using Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR MS), are important. FT-ICR MS has been successfully used to analyze complex environmental organic molecule mixtures such as natural, soil, particulate, and dissolved organic matter. Despite its success, many limitations still need to be overcome. Sample preparation, ionization, structural identification, chromatographic separation, and data interpretation are some key areas that have been the focus of numerous studies. This review describes key developments in analytical techniques in these areas to aid researchers seeking to start or continue investigations for the molecular-level understanding of environmental organic compound mixtures.

超高分辨率质谱法分析环境有机物——分析方法发展综述

由于全球环境和气候变化的增加,人们对环境有机化合物混合物的分子水平理解越来越感兴趣,即追求对化学成分和相关化学反应的完整和详细的了解。环境有机分子混合物,包括空气、土壤、河流和海洋中的有机分子混合物,具有极其复杂和异质的化学成分。对于他们的分析,使用傅里叶变换离子回旋共振质谱 (FT-ICR MS) 可实现的超高分辨率和亚 ppb 级质量精度非常重要。FT-ICR MS 已成功用于分析复杂的环境有机分子混合物,例如天然、土壤、颗粒物和溶解的有机物。尽管取得了成功,但仍有许多限制需要克服。样品制备、电离、结构鉴定、色谱分离和数据解释是许多研究关注的一些关键领域。这篇综述描述了这些领域分析技术的关键发展,以帮助寻求开始或继续调查环境有机化合物混合物的分子水平的研究人员。
