A system, device, and a method for determining a compound content in transformer oil are provided. The method includes positioning a syringe filled with transformer oil in the device to transfer the oil to a vial using the device. The device includes a stand, a threaded rod, a handle, a disc, and a syringe holder. The threaded rod is movable in a vertical direction by rotation of the handle and is configured to apply pressure via the disc on a plunger of the syringe positioned in the syringe holder to maintain an airtight connection between the vial and the device. The compound content is determined using a gas chromatograph by analyzing an aliquot extracted from a headspace gas of the vial.

A method of analyzing fuel component using an RF (Radio Frequency) sensor for a vehicle includes: receiving a new fuel into a fuel tank so as to mix existing fuel in the fuel tank with the new fuel, measuring a resonance frequency of the mixed fuel using an RF sensor, comparing the measured resonance frequency of the mixed fuel with a resonance frequency of a standard fuel, determining whether the mixed fuel is a normal fuel through the comparison, maintaining an engine combustion pattern corresponding to the standard fuel when the mixed fuel is a normal fuel, and operating reflecting an engine combustion control.

A method of directly analyzing an environmental sample, such as a crude oil sample, to simultaneously determine distillation ranges, identify elements therein, and/or identify impurities. The method includes performing multi-element scanning thermal analysis (MESTA) on the crude oil sample to obtain a thermogram of the elements within the crude oil sample, wherein peak information within the thermogram indicates presence of the elements, compounds, and/or impurities within the crude oil sample.

Measuring the real corrosion risk that organosulfur compounds present in refinery operations is simplified by first measuring the total sulfur content of a sample of a hydrocarbon material. The sample is then combined with a specific quantity of high surface area iron powder at a temperature representative of the highest temperature anticipated in a refining process for a period of time, such as one hour. The solid phase is then removed, and the total sulfur content is again measured. The difference between the before and after represents the total reactive sulfur of the hydrocarbon material. The hydrocarbon material is then blended with other hydrocarbon materials to create a stream that can be optimized to utilize the maximum volume of the lowest cost feedstock while managing the corrosion risk to the refinery equipment and piping.

An RF sensor device for a vehicle is provided. The RF sensor device includes a patch type RF sensor including a first patch sensor attached to an outside of a fuel tank and a second patch sensor attached to the outside of the fuel tank to face the first patch sensor, and a function generator for connecting the first patch sensor and the second patch sensor through a ground patch and function converting the electrical signals of the fuel contained in the fuel tank detected by the first patch sensor and the second patch sensor.

The present invention relates to method for assessing the H.sub.2S release capacity of a liquid sample containing one or more sulfur compounds which are able to be degraded into gaseous H.sub.2S with temperature. The method comprising: a) Placing a volume of the liquid sample in a purge vessel so as to obtain a liquid phase and a gaseous phase in a flask; b) Purging the gaseous phase with an inert gas stream for a determined period of time; e) Passing the purged gaseous phase through a H.sub.2S trap; d) Recovering H.sub.2S from the H.sub.2S trap; and e) Dosing the recovered H.sub.2S. The invention is also used in a method for selecting a liquid sample, in particular among a group of different liquid samples.

Quantifying an amount of sulfur in a petroleum sample includes sequential extraction and quantification of inorganic and organic sulfur species. An exemplary process includes extracting inorganic sulfur components from the sample to yield extracted inorganic sulfur components and a residual sample, and reducing the sulfur in the extracted inorganic sulfur components to yield a first quantity of hydrogen sulfide. The organic sulfur components are extracted from the residual sample to yield extracted organic sulfur components, and the sulfur in the extracted organic sulfur components is reduced to yield a second quantity of hydrogen sulfide. The amount of sulfur in the first quantity of hydrogen sulfide and the amount of sulfur in the second quantity of hydrogen sulfide are combined to yield a total amount of sulfur in the sample.
