    摘要： A microfluidic system for performing fluid analysis is described having: (a) a submersible housing having a fluid analysis means and a power supply to provide power to said system; and (b) a substrate for receiving a fluid sample, having embedded therein a fluid sample inlet, a reagent inlet, a fluid sample outlet, and a mixing region in fluid communication with the fluid sample inlet, the reagent inlet, and the fluid sample outlet, and wherein the substrate includes a fluid drive means for moving the fluid sample through the substrate, and wherein the substrate interconnects with the housing. At least a portion of the fluid analysis means may be embedded in the substrate.

    摘要： Described herein are variable-volume reservoir (e.g., syringe pump) based processes and systems usable to characterize samples of reservoir fluids, without having to first transport the fluids to the surface. Variable-volume reservoirs are used, for example, for one or more of storing reactants, controlling mixing ratios and storing used chemicals. The processes and systems can be used in various modes, such as continuous mixing mode, flow injection analysis, and titrations. A fluid interrogator, such as a spectrometer, can be used to detect a change in a physical property of the mixture, which is indicative of an analyte within the mixture. In at least some embodiments, a concentration of the analyte solution can be determined from the detected physical property.

    摘要： Methods and devices for detecting a concentration of one or more element in hydrocarbon and/or natural gas in a oil and gas field application. The device including a microstructure having a low thermal mass suspended within a channel, the microstructure includes a supporting layer and a insulating layer; a controllable thermal device in communication with the supporting layer of the microstructure, wherein the controllable thermal device is controllably heated to one or more release temperature of the one or more element; a sensing layer arranged on the insulating layer to absorb molecules of the one or more element from hydrocarbon and/or natural gas; a detecting and measuring resistance device in communication with the sensing layer for measuring the resistance changes caused by absorption of molecules of the one or more element onto the sensing layer at a first temperature and a second temperature, and storing the data on a processor.
