| Progress in the Application of Orbitrap Mass Spectrometry in the Characterization of Dissolved Organic Matter in Water |
| Dissolved organic matter (DOM) exists widely in the aquatic ecological environment and has a significant influence on the biogeochemical properties of many substances. Its composition and content have important ecological and environmental significance and has been a hot spot in ecological and environmental science research. The composition of DOM is complex, and its molecular composition analysis has always been a challenge. In recent years, Orbitrap mass spectrometry (Orbitrap MS), capable of high resolution, high sensitivity, high throughput, and high scanning rate, combined with computer programming technology and visualization technology could be used to characterize the molecular composition and distribution of DOM, greatly improving the capabilities of DOM. In this paper, the explanation methods of DOM high-resolution MS data are summarized, the Orbitrap MS technology and its application status in characterization of DOM in water are reviewed, and the prospects for future developments are analyzed. |
