Analysis of oxygen-containing polycyclic aromatic compounds by gas chromatography with atomic emission detection

Chemicals from Direct Coal Liquefaction

“…Aczel et al also identified the sulfur compounds present in a heavy hydrogenated fraction (≥700 °F): C n H 2 n –4 S (MW 126, 4 × 10 –3 ), C n H 2 n –16 S (MW 226, 3 × 10 –3 ), C n H 2 n +8 S (MW 231, 2 × 10 –3 ), and C n H 2 n –20 S (MW 252, 5 × 10 –3 ). Wu et al , did not detect by ESI FT-ICR mass spectroscopy on sulfur-containing class, which may have been related to the low ionization efficiency of sulfur by ESI.…”

“…Bartle et al used a GC–AED to detect the dibenzofurans in the coal oil derived from Spanish coal, which had been liquefied at 400 °C with a process-derived hydrogenated solvent. Sumbogo et al , also used this technique to identify phenol, alkylphenols, alkylbenzofurans, and alkyldibenzofurans in the liquid products of the gas oil fraction derived from Tanito Harum and South Banko coals (SBCL).…”

“…Bartle et al 43 used a GC−AED to detect the dibenzofurans in the coal oil derived from Spanish coal, which had been liquefied at 400 °C with a process-derived hydrogenated solvent. Sumbogo et al 33,34 treatment of the oxygen-containing chemicals in the coal-derived gas oil fraction has been explored as an approach to upgrade this fraction.…”

Opportunities and challenges for the application of post-consumer plastic waste pyrolysis oils as steam cracker feedstocks: To decontaminate or not to decontaminate?

“…The GC (× GC)-effluent is directed into a He plasma chamber where all elements are atomized and excited. When the atoms transition from the excited to the relaxed state, radiation at a characteristic wavelength for every element is released and detected ( Tranchida and Mondello, 2019 , Bartle et al, 2009 ).…”

Determination of the volatiles from tobacco by capillary gas chromatography with atomic emission detection and mass spectrometry

“…With GC-AED, the elements were in groups on the condition that close emission line wavelengths and the same scavenger gases were used [27]. For this reason, three sequential chromatographic runs were required to obtain chromatograms for C, H and O.…”
