The biogeochemical cycling of soil organic matter (SOM) plays a central role in regulating
soil health, water quality, carbon storage, and greenhouse gas emissions. Thus, many …

We describe complex organic mixture analysis by 21 tesla (T) Fourier transform ion cyclotron
resonance mass spectrometry (FT-ICR MS). Ultrahigh mass-resolving power (m/Δ m 50%> 2 …

For decades, discussion of asphaltene structure focused primarily on molecular weight. Now
that it is widely accepted that asphaltene monomers are between∼ 250 and 1200 g/mol …

Global wildfire activity has increased since the 1970s and is projected to intensify throughout
the 21st century. Wildfires change the composition and biodegradability of soil organic …

Advances in high-resolution Fourier transform ion cyclotron resonance mass spectrometry
(FT-ICR MS) enable molecular-level characterization of ultracomplex asphaltene samples …

Asphaltene structure is one of the most controversial topics in petroleum chemistry. The
controversy is centered on the organization of aromatic cores within asphaltene molecules …

Dissolved organic matter (DOM) is a complex mixture of organic compounds, which is of
significant relevance in the context of drinking water treatment. This importance stems from …

Wildfires in forested watersheds dramatically alter stored and labile soil organic matter
(SOM) pools and the export of dissolved organic matter (DOM). Ecosystem recovery after …

Fourier ion cyclotron resonance mass spectrometry (FT‐ICR MS), one of the state‐of‐the‐art
ultrahigh‐resolution techniques, is widely used in dissolved organic matter (DOM) research …

Ultrahigh resolution mass spectrometry is widely used for nontargeted analysis of complex
environmental and biological mixtures, such as dissolved organic matter, due to its …
