  Fluorine Content in Fluoride Toothpaste Tested by Low-Field NMR

  February 28, 2023 Applications / Benchtop NMR / Life Science

  The NMR method is based on the linear relationship between the content of fluorine nuclei in the sample and the intensity of the NMR signal. The NMR signal amplitude is proportional to the mass of soluble fluorine, and through this linear relationship, the fluorine content of the sample to be tested can be quickly detected.

  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.

  Solid Fat Content Measurment by NMR

  February 21, 2023 Applications / Articles / Food & Agriculture

  Pulsed NMR is the only direct measurement of solid fat content (SFC), unlike indirect methods such as differential scanning calorimetry (DSC) and dilatometer, which obtain results by measuring the melting point (i.e., the volume change resulting from solid phase melting).
