    摘要： Methods and related systems are described for high pressure chromatographic analysis. The described system includes a flowpath adapted to flow a mobile phase and the sample at high pressures, an injector adapted to inject the fluid sample into a flowpath, a separation column adapted to operate at high pressures for separating various components, a detector and a processor that calculates the amount of at least one component of the fluid sample. The system can operate a pressures above 20 atm or even 100 atm, and temperatures above about 100 degrees Celsius. The system can deployed in a wellbore in a subterranean rock formation, and include fluid collection system for obtaining the fluid sample downhole. The system can also be located close to a wellhead and includes a tap in fluid communication with a surface flowline carrying produced fluids and the injector.

    摘要： The operation, analysis and interpretation of a chromatographic system can be significantly enhanced by coupling therewith one or more fluid property measurements that provides an initial indication of the fluid type, the presence of any contamination, an estimate of the hydrocarbon composition (C1, C2-C5 and C6+), gas/oil ratio, color and/or fluorescence measurements. Other measurements that can be used in the initial stage can include density, viscosity, phase transition determinations. These measurements may be used to enhance, in real-time, the GC sampling protocol, the analysis protocol and also improve the robustness of the interpretation of the chromatogram.

    摘要： A self-contained micro-scale gas chromatography system that includes a plurality of gas chromatography components arranged on a micro-fluidic platform with nearly zero dead volume “tubeless” fluidic connections for the gas chromatography components. The micro-fluidic platform includes a plurality of flow channels that provide fluid flow paths for a sample, carrier gas and waste gas through and among the micro-fluidic platform and the plurality of gas chromatography components. The gas chromatography components may include a micro-scale gas chromatography column that is implemented as a MEMS device and includes embedded heating and cooling elements. The system may also include an on-board supply of carrier gas and on-board waste management, as well as a thermal management scheme making the system suitable for use in oil and gas wells and also other remote environments.

    摘要： A heat switch for remote self-contained gas chromatography is disclosed. The device mechanically separates a hot or cold reservoir from the chromatography column when heating or cooling is not needed. The column needs a cooling system to obtain initial temperatures below ambient. At other times the column needs to be heated to relatively high temperatures, during which time the cooling system is preferably detached. The heat switch allows for rapid temperature changes while minimizing the peak cooling power requirement.
