A rapid method to assess a broad inventory of organic species in marine sediments using ultra‐high resolution mass spectrometry

Abstract

The reported method enables rapid (12 min FTICR-MS analysis time) and simultaneous detection of a broad range of multi-heteroatom, polar organic species in whole sediment extracts. This allows for higher sample throughput, a more comprehensive investigation of sedimentary geochemistry, and potentially the discovery of new components and derivation of novel, multi-species proxies.

Mechanistic insights into sulfur rich oil formation, relevant to geological carbon storage routes. A study using (+) APPI FTICR-MS analysis

“…On the other hand, both Jianghan and Rozel Point oils show mass spectra that reflect a dominant signature of precursor compounds (Fig. 3C), somewhat akin to the spectra observed in recent marine sediments (Radović et al, 2016a), a consequence of the low thermal stress levels experienced by these oils. Thus, both Rozel Point and Jianghan oil (+) APPI FTICR-MS mass spectra are a good representation of the chemical species and mechanisms involved in early diagenesis and related sulfur incorporation processes.…”

“…Carotenoids are the likely biological source for C40 species, since they are common constituents of living organisms with wide taxonomic diversity, from archaea and cyanobacteria to higher plants and animals (Walter and Strack, 2011). Recently, we used a similar (+) APPI FTICR-MS approach to characterize carotenoids in recent marine sediments, in addition to various other lipid markers (Radović et al, 2016a). Whereas C27-30 S-bearing steroids appear to be limited to classes S1-2 (see Section 4.3.…”

Multi-proxy assessment of surface sediments using APPI-P FTICR-MS reveals a complex biogeochemical record along a salinity gradient in the Pearl River estuary and coastal South China Sea

“…Only recently, developments of single-run methods that allowed investigators to simultaneously monitor multiple proxies of interest have emerged; notably, these novel methods use Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) leveraging the capability of this analytical platform to screen for thousands of compounds, with a very high resolution over a broad analytical window of polarity and molecular weights. [3][4][5][6][7][8][9] While FTICR-MS approaches may lack the sensitivity and separation specificity of liquid chromatography-based approaches, they have an advantage of simplified sample preparation, and the screening capability that can discover novel geochemical proxies and pathways. 6,7 With a length of ~2,400 kilometers, the Pearl River (PR) is the second largest river in China.…”

Visualization of57Fe-Labeled Heme Isotopic Fine Structure and Localization of Regions of Erythroblast Maturation in Mouse Spleen by MALDI FTICR-MS Imaging

“…Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) is used to analyze extremely complex mixtures such as crude oil [ 8 ], proteome [ 9 ], and metabolome samples [ 10 ] because of its ultrahigh resolution (>1,000,000 full width at half-maximum at 7.0 T) and high mass accuracy (<1 ppm). Ultrahigh resolution mass spectrometry is also used to determine unknown compounds [ 11 ]. The ultrahigh resolution of FTICR-MS enable clear separation of stable isotopes such as 13 C, 15 N, 34 S, and 18 O, and the high mass accuracy allows candidates elemental compositions [ 12 ].…”
