Abstract:
Oxygen is one of the most abundant components of organic compounds, and its analysis is now essential across a broad range of scientific fields (petroleomics, metabolomics, environmental sciences) and numerous industrial applications (hydrocarbon processing, new energies, natural gas, and biogas, pharmaceuticals, chemicals and additives manufacturing). For this reason, is crucial the detection and quantification of individual oxygen compounds in real complex samples.
Current alternatives for oxygen detection, including Oxygen-flame ionization detector (O-FID) or Mass Spectrometry which are strongly affected by sample matrix and quenching, do not meet the sensitivity, selectivity, and robustness requirements needed to detect traces of oxygenates in complex fuel matrices such as biomass energy, biofuels, chemical recycling, and pyrolysis oils. Additionally, these samples often require specific standards for accurate quantification of specific oxygen- and nitrogen-containing compounds. The ELEM-SPOT™ is the first element-selective gas chromatograph mass spectrometer which utilizes isotopic oxygen combustion mass spectrometry to address these challenges.
