Amides in Bio-oil by Hydrothermal Liquefaction of Organic Wastes: A Mass
Spectrometric Study of the Thermochemical Reaction Products of Binary
Mixtures of Amino Acids and Fatty Acids
Authors: Chiaberge S., Leonardis I., Fiorani T., Bianchi G.
Abstract: All of the amides present in the bio-oil have been recognized as hydrothermal
coupling compounds of the decomposition products of amino acids with fatty acids,
thus allowing for their structural elucidation and, also important, confirming their
(bio)chemical origin.

Enhanced Sensitivity for Biomarker Characterization in Petroleum Using Triple
Quadrupole GC/MS and Backflushing
Authors: Churley, Prest
Abstract: A rapid, reliable method for the routine detection and quantification of biomarkers in
petroleum was developed using the Agilent 7890A/7000A Series Triple Quadrupole
GC/MS with backflushing using a Pressure Controlled Tee configuration. In a single
run, diverse biomarkers from several transitions can be detected, confirmed, and
quantified at levels as low as 2 ppm, with RSDs well below 5%. This method is
suitable for "fingerprinting" of petroleum samples and the deconvolution of oil mixtures
in complex, multisource petroleum systems.

Methyldibenzothiophene isomer ratio in crude oils: Gas chromatography
tandem mass spectrometry analysis
Authors: Chiaberge S., Fiorani T., Cesti P.
Abstract: MDBT isomers are used for the characterization of crude oils, without fractionation.
Backflush is used with the GCTQ.

Graben: implications for petroleum prospectivity evaluation in an Upper
Jurassic sandstone play area
Authors: Petersen H.I., Nytoft H.P., Vosgerau H.
Abstract: Jurassic rocks are tested for oil composition and their sourcing. Kerogen (Greek
κηρός "wax" and -gen, "that which produces")[1] is a mixture of organic chemical
compounds that make up a portion of the organic matter in sedimentary rocks.[2] It is
insoluble in normal organic solvents because of the high molecular weight (upwards
of 1,000 daltons or 1000 Da; 1Da= 1 atomic mass unit) of its component compounds.
The soluble portion is known as bitumen. When heated to the right temperatures in
the Earth's crust, (oil window ca. 60–160 °C, gas window ca. 150–200 °C, both
depending on how quickly the source rock is heated) some types of kerogen release
crude oil or natural gas, collectively known as hydrocarbons (fossil fuels). When such
kerogens are present in high concentration in rocks such as shale they form possible
source rocks. Shales rich in kerogens that have not been heated to a warmer
temperature to release their hydrocarbons may form oil shale deposits.
