  Time domain NMR (TD-NMR)

  March 22, 2021 Articles / Blog / Food & Agriculture

  Time domain NMR (TD-NMR) Time domain NMR (TD-NMR) is a magnetic resonance technique based on relaxation time detection. Time domain NMR is generally tested and analyzed by T1 and T2 relaxation time. It is an advanced characterization method, and the test process is fast and non-destructive. Time domain NMR has been widely used in scientific research and industrial quali ...

  Benchtop MRI Study on the Contact Angle of the Solid-Liquid Interface

  March 18, 2021 Articles / Blog

  Benchtop MRI Study on the Contact Angle of the Solid-Liquid Interface Benchtop MRI can be used to obtain images of water-glass-oil interface and water-glass-benzene interface that are difficult to obtain by ordinary optical methods, and the contact angle of the interface can be studied by Benchtop MRI technology. The measurement of the contact angle of transparent liqu ...

  Why do NMR Analyzer need a highly uniform and stable magnetic field?

  January 21, 2021 Blog

  A key index to evaluate the performance and quality of NMR magnets is the uniformity and stability of the magnetic field. The uniformity and stability of the magnetic field directly affect the imaging quality, image resolution and imaging artifacts of MRI. Uniformity of magnetic field Magnetic field uniformity refers to the uniformity of the main magnetic fiel ...

  D-T2 Spectra——Rock Core NMR

  January 15, 2021 Blog

  Although one-dimensional spectra such as relaxation spectra and diffusion spectra have achieved great success in the analysis of core properties, a single parameter or one-dimensional spectrum often cannot fully reflect the properties of the Rock Core NMR and the distribution of oil and water in the core. One-dimensional spectrum cannot distinguish oil from water very clear ...

  2D time-domain spectrum in low-field NMR

  November 26, 2020 Blog

  Time domain nuclear magnetism (TD-NMR) is different from conventional frequency domain analysis. The term "time domain" is embodied in that it mainly uses relaxation time or time domain signals (chemical shifts in the non-frequency domain) for detection and analysis. Low-field NMR (generally Bo<0.5T) is the most fundamental analysis method. The application range of TD-NM ...

  Advantages of LF NMR

  November 13, 2020 Blog

  NMR is often performed in massive magnetic fields for 3 reasons: to enhance chemical shift resolution, to maximize the sensitivity of detection by inductive coils, and to extend the magnitude of the measured signal by enhancing thermal polarization LF NMR. However, these benefits come back at a literal and figurative price – trendy superconducting magnets with sufficient ho ...
