Abstract: A method of incorporating the influence of diffusion into the CPMG-based T2 measurement for one or more of the following: water cut measurement; performing inline measurements of flow rate; density; and rheology of a flowing fluid. The method includes conducting a “standard T1/T2 experiment” at least twice by providing one scan without a field gradient during the CMPG echo train. Then, providing a second scan with the application of a gradient, where in the second experiment the measured T2 (T2app) is affected solely by water diffusion, thus shifting cross peaks which represent water on the first T1/T2 spectrum to lower T2 values on the second spectrum.

Abstract: A method for a NMR device to determine NMR measurement results of a sample from a set of RF signals emitted by the sample and received by the NMR device is disclosed. The method can include: receiving a plurality of RF signals emitted by the sample; determining a phase shift of each signal of the plurality of RF signals; correcting a phase of each signal of the plurality of RF signals; determining a frequency shift of each signal of the plurality of RF signals; shifting each signal of the plurality of RF signals to the predetermined; correcting an additional phase shift of each signal of the shifted plurality of RF signals to generate corresponding plurality of corrected RF signals; and averaging the corrected RF signals to determine the NMR measurement result. In some embodiments, the receiving, determining, correcting, shifting and/or averaging is done by the NMR device.

The system can be hand handled by a user, located on a production line or placed a laboratory. The system can include a Nuclear Magnetic Resonance (NMR) spectrometer and a controller. The controller can be configured to: receive an NMR spectrum of the processed food product from the NMR spectrometer, identify a first peak related to a first component of the processed food product from the received NMR spectrum and determine the quality of the processed food product based on the identification. The controller may further configured to control parameters of the production line based on the determined quality.

Abstract: A nuclear magnetic resonance (NMR) probe cassette, with a removable conduit body made of a non-magnetic material having a longitudinal axis with an opening at one end, centered on the axis. The conduit body is reversibly connected to a heat exchanger to substantially maintain the conduit body at a predetermined temperature. The NMR probe cassette also includes a second conduit made of a non-magnetic material. The second conduit extends through the central opening in the first conduit body and is configured to receive and contain a sample. Still further, the NMR probe cassette includes a processor and computer readable media with instructions for controlling the heat exchanger.

Abstract: The present disclosure is generally related a method for the liquefaction of high-solids biomass substrates. Particularly, biomass can be added to a reactor until a pressure drop, measured inline, reaches the maximum system limitations. A commercial enzyme mixture (specific for the particular type of biomass to be processed) may then be added to the biomass, forming a slurry. The pressure may be continuously monitored and when the pressure drop reaches a steady state (which can be determined by little or no change in pressure drop for several minutes), more biomass may then be added until the high pressure limit of the pump system is reached again. The method can be repeated until the desired quantity of biomass is processed.
