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

Boreal lakes are considered hot spots of dissolved organic matter (DOM) processing within
the global carbon cycle. This study has used FT-ICR mass spectrometry and comprehensive …

A prior method of mass labeling ketone-/aldehyde-containing species in natural dissolved
organic matter (DOM) is further developed and applied. This application involved the …

This study focuses on the deterministic task of assigning molecular formulae to exact
masses that are generated by ultrahigh resolution mass spectrometry. A new algorithm …

The composition of the juice from grape berries is at the basis of the definition of
technological ripeness before harvest, historically evaluated from global sugar and acid …

Ultra-high resolution mass spectrometers produce large amount of MS and MS/MS spectra,
whose interpretations may not be easy even for experts in this field. Noise among other …

Ultra-high resolution mass spectrometers (UHR MS) including Fourier Transform ion
cyclotron resonance (FT-ICR MS) and Orbitrap mass analyzers produce data of ever more …

What molecular formulae correspond to a given mass M? Here, we address this problem—
the compomer problem of mass spectrometry. We describe, implement, and test a …

Organic aerosol affects human health and climate. These effects are largely determined by
the composition of the organic aerosol, which is a complex mixture of species …

Blueberries and cranberries have vastly different flavor profiles despite both being a part of
the Vaccinium genus. Their high content of phenolics makes them subjects of interest in …
