The invention relates to a method for monitoring a process for refining a feedstock of hydrocarbons, in which: a) a signal representative of the transverse relaxation time of the different entities of an effluent resulting from said refining process, in particular an effluent comprising solid entities, is acquired by proton NMR, b) the signal measured is modeled using a mathematical function comprising several components, each component corresponding to a dynamic range of the entities of said effluent, c) the following are extracted from each of the components of the mathematical function: the transverse relaxation time of each of the components, the intensity of each of the components, d) a value of parameter characteristic of said effluent is determined from at least one intensity determined in stage c), e) a signal for controlling the refining process is generated as a function of said characteristic parameter.

A mobile measuring device, in particular a hand-held measuring device, comprises a housing, in which at least one sensor device, a control device for controlling the sensor device, an evaluation device for evaluating the measurement signals supplied by the sensor device as well as a device for supplying energy to the measuring device are provided. The sensor device comprises at least one nuclear spin resonance sensor which is provided at least for the detection and/or analysis and/or differentiation of a material characteristic of a workpiece, in particular in a workpiece.

A mobile measuring apparatus for nondestructively determining a material measurement value that relates to a material property of a workpiece comprises a housing in which at least a first sensor device and a second sensor device are located, a control device, an evaluating device, and a device for the supply of energy to the measuring apparatus. The first sensor device has a nuclear magnetic resonance sensor and the second sensor device has a sensor based on dielectric and/or resistive methods. Information about the material property of the workpiece, in particular moisture present in the workpiece, is obtained by evaluating a measurement signal provided by the first sensor device, which information is intended for the optimized control of the second sensor device and/or optimized evaluation of measurement signals provided by the second sensor device.

A gas oil separation plant (GOSP) and method for receiving crude oil from a wellhead and removing gas, water, and salt from the crude oil, and discharging export crude oil. The GOSP includes online analyzer instruments for performing online analysis of salt concentration in multiple streams in the GOSP. Based in part on the online analysis, the salt content in the export crude oil may be determined and the flowrate for wash water supplied to the desalter vessel may be specified.

A method of predicting the responsiveness of a patient to a pharmaceutical drug by measuring metabolites in a biological sample from the patient is disclosed. Specific drug metabolites in blood from breast cancer patients are analyzed using NMR spectroscopy whereby responsiveness of the human cancer patients before, during and after treatment with a cancer drug is assessed by measuring the change in clinical outcomes. Data obtained is used to identify particular NMR resonances that are strongly correlated with whether the patient is responsive or resistant to each drug. As such, models for predicting the responsiveness of a patient to each drug based on metabolites from the patient are provided.

A point-of-care diagnostic system that includes a cartridge and a reader. The cartridge can contain a patient sample, such as a blood sample. The cartridge is inserted into the reader and the patient sample is analyzed. The sample can be processed for data collection and analysis to provide interpretative results indicative of a disorder, condition, disease and/or infection of the patient. For example, the data collection and analysis can differentiate between two or more species capable of causing or actually causing a parasitic infection.

A device and method is described to parallelize a pressure-volume-temperature (“PVT”) analysis using gas chromatography and mass spectrometry techniques such that a portion of the pressure, temperature and volume analysis is performed separately from others. The resulting PVT data is then recombined statistically for a complete PVT analysis. The device may also obtain compositional data of the fluid to perform an equation of state analysis or reservoir simulations.

A method of measuring petrophysical information from a crushed porous media including performing one or more NMR measurements on the porous media fully submerged in an NMR visible fluid, performing one or more NMR measurements on the porous media alone following centrifugation, performing one or more NMR measurements on the porous media after rinsing with a NMR invisible fluid, and analyzing the NMR measurements to extract a petrophysical property.

The present invention relates to a method based on proton NMR technique to differentiate genuine and spurious Hand-rub formulations. This method identifies and estimates all four components present in WHO-recommended Hand-rub formulations. Further, this method also identifies the presence of non-recommended/additional components present in WHO-recommended Hand-rub formulations. The method described in this invention utilizes experimental parameters and derived equations to quantify all four components in just fifteen minutes without using any organic solvents.

An NMR measurement apparatus includes a transmitting antenna including a transmitter coil, a capacitor, a dissipating component and a restricting component, and a receiving antenna physically separated from the transmitting antenna. A processor is configured to apply a drive signal at a first voltage level to generate a transmission signal having a selected transmission frequency, where the receiving antenna is deactivated during generation, connect the dissipating component to the transmitter coil to dissipate stored energy in the transmitter coil, connect the restricting component to the transmitter coil to restrict the transmitting antenna to a second voltage level smaller than the first voltage level and based on a voltage of NMR signals from the sensitive volume, activate the receiving antenna and detect a NMR signal, where the restricting component is connected to the transmitter coil and restricts the transmitting antenna during the activating and the detecting.
