  Relaxation Time of NMR

  March 31, 2023 Applications / Articles / NMR Principle

  The relaxation process is the process of energy release. The spin lattice is equivalent to the lattice composed of H atoms, so the energy is released into the surrounding lattice. T1 relaxation is closely related to the motion of surrounding molecules. T1 can study slow molecular motion, such as the chelation state of metal ions, protein aggregation, surface dynamics of por ...

  Low Field NMR Introduction

  February 28, 2023 Applications / Articles / More NMR MRI / NMR Principle

  Low Field NMR Introduction   What is low-field NMR? NMR instruments can be divided into the following categories according to the strength of the magnetic field: >3.0T ——-high field strength NMR. 1.0T-3.0T —–Medium field strength NMR. 0.1T-1.0T ——–low field strength NMR. <0.1T ——Ultra-low field strength NMR. Low-field NMR mainly refers to NM ...

  Pulsed NMR Advantages

  February 28, 2023 Applications / Articles / NMR Principle

  Pulsed NMR Advantages Pulsed NMR (Nuclear Magnetic Resonance) is a technique used in spectroscopy to study the structure and dynamics of molecules in solution. It works by exploiting the magnetic properties of atomic nuclei, specifically the behavior of their magnetic moments in an external magnetic field. In pulsed NMR, a sample is placed in a strong, uniform magne ...

  Low-field NMR Can Test Multiple Samples

  February 28, 2023 Applications / NMR Principle

  Low-field NMR Can Test Multiple Samples A low-field NMR instrument is a type of nuclear magnetic resonance (NMR) spectrometer that operates at low magnetic field strengths, typically in the range of a few tens of milliTeslas (mT) to a few Teslas (T). In contrast, high-field NMR instruments operate at much higher magnetic field strengths, typically in the range of sever ...

  Time domain NMR（TD-NMR）

  February 21, 2023 Applications / Articles / More NMR MRI / NMR Principle

  In the time domain NMR instrument, we use infinite electric waves to excite the sample to make the atomic nucleus at the bottom energy level transition to the high energy level.

  Low Field NMR

  January 31, 2023 Applications / Articles / NMR Principle

  First of all, it should be noted that there is an important parameter in NMR called Gyromagnetic ratio, which is related to the nucleus.
