Структура настольного ЯМР, ядерный магнитный резонанс
The architecture of Benchtop NMR:
Настольный ЯМР can be divided into four parts: магнит, радиочастота, spectrometer and temperature control.
Магнит: providing uniform magnetic field;
RF Unit: RF amplification and signal excitation;
Spectrometer: a control system for Benchtop NMR;
Temperature control: accurate temperature control of the magnet;
Настольный ЯМР is compact, экономически эффективным, легко использовать, simple daily maintenance, can provide a variety of applications. Temperature-controlled permanent magnets do not require liquid nitrogen and helium, and have low cost of use and maintenance. They are suitable for a variety of laboratory research and enterprise quality control.
How Benchtop NMR works:
Benchtop NMR mainly corresponds to H for detection, and can also be used for F signal testing. The NMR signal is generated after the sample is excited by a specific frequency RF pulse. T1 and T2 are the two main parameters. By testing the T1 and T2 relaxation time, его можно использовать в пищу, сельское хозяйство, petroleum exploration, polymer, содержание твердого жира… Multiple studies. Various methods have been developed to form international standards and industry standard methods.
The main features of Benchtop NMR:
1. Friendly user interface, easy to operate. It is simple to use and does not need professional and technical personnel to operate.
2. Benchtop NMR is small, no need special installation site.
3. постоянный магнит, Convenient maintenance, low cost.
