Pyrolysis to determine hydrocarbon expulsion efficiency of hydrocarbon source rock
An open system pyrolysis of a first hydrocarbon source rock sample obtained from a natural system is performed within a pyrolysis chamber by maintaining the pyrolysis chamber at a substantially constant temperature. Hydrocarbons are recovered from the pyrolysis chamber released by the first hydrocarbon source rock sample. A thermo-vaporization is performed within the pyrolysis chamber on the pyrolyzed sample at a substantially constant temperature. A first hydrocarbon expulsion efficiency of hydrocarbon source rock is determined. A second hydrocarbon rock sample is ground to a grain size less than or equal to or less than 250 micrometers. A second pyrolysis is performed on the ground hydrocarbon source rock sample by maintaining the chamber at a substantially constant temperature. A second hydrocarbon expulsion efficiency of the hydrocarbon source rock in the natural system is determined. The first hydrocarbon expulsion efficiency is verified using the second hydrocarbon expulsion efficiency.

Automated apparatus for sample pyrolysis
An apparatus for generating gas from a sample (battery) by pyrolysis of the sample in order to collect or analyze gas generated inside the sample due to the thermal behaviors of the sample. More specifically, provided is an apparatus wherein not only gas generated due to the thermal behaviors of a sample (battery) can be generated by heating the sample (battery itself), but also a series of processes provided to collect or analyze the generated gas can be automatically controlled.
DETECTION AND IDENTIFICATION OF CHEMICAL DERIVATIVES FORMED FROM PYROTECHNIC SMOKE REACTIONS
Provided is a method to initiate and analyze chemical derivatives formed from pyrotechnic smoke reactions. Milligram quantities of a lab-scale pyrotechnic smoke composition are reacted by encapsulation with a metal probe that is rapidly heated, which then sublimes the organic dye, allowing for the testing of all of the gas-phase products for identification by pyrolysis-gas chromatography-mass spectrometry. The thermally decomposed ingredients and new side product derivatives are identified at lower relative abundances compared to the intact organic dye. Any remaining residues within the thermal probe are optionally reconstituted into solution for further analysis by liquid chromatography-mass spectrometry if desired. The results are processed via a machine learning quantitative structure-activity relationship model that provides data related to health and environmental hazards.
SYSTEM AND METHODS FOR MONITORING LEAKS IN UNDERGROUND STORAGE TANKS
Leak detection system and method for monitoring leaks in underground and aboveground storage tanks, pipelines or other containments, including single, double or triple wall containments are provided. A leak detection apparatus includes an oxidation chamber, a chemical marker concentrator, a mass spectrometer (MS) ion trap and a scroll vacuum pump. Vapor samples carrying marker chemicals introduced into a tank, pipeline, or other containment are injected at sample injection point into an oxidation chamber. Oxygen from an oxygen source is fed into oxidation chamber to destroy or oxidize contaminates such as hydrocarbons in the vapor without destroying or oxidizing the chemical markers. Effluent from the oxidation chamber is passed to an elongate conduit with a metal foil or screen suspended within the conduit. The marker chemicals are attracted by a chemical coating on the foil/screen and released by heating the metal. The released marker chemicals are fed into a mass spec ion trap for leakage analysis and results.
