Obvious resonance signal

Base on the state-of-the-art design on the detection unit, We can achieve the obvious resonance signal.

The detection position can be adjustable in the magnetic field

Detector mounted on an adjustable poster, and adjust poster mounted on the track. The detector and sample could be adjusted in the horizontal and vertical directions.

Provide a vessel for user-supplied sample

In addition to H + and F- sample ship together with NMR apparatus, but also provides a vessel user-supplied sample, allows users to test a nuclear magnetic resonance phenomenon user-supplied material.

Adjustable 0-300mT uniform magnetic field

Magnetic Field including to electromagnetic coil and excitation power supply, can be set in 0-300mT range, and high uniformity.

Typical Experiments and data

1. Observe the NMR of H+ and F- samples

NMR of water sample

NMR of PTFE sample

2. Calculate the g factor of H+ and F-

g= hυ/μn•B0,
h=6.626×10-34J • s,   μn =5.051×10-27J / T,
gH=5.5857；gF=5.2567.
The relative error is less than 5%.
