Nuclear Magnetic Resonance (NMR) Instrument 

Main experimental content
1、Master and understand the principle and phenomenon of nuclear magnetic resonance (NMR).
2, can observe 1H and 19F nuclear magnetic resonance signal, measurement of gN value and nuclear magnetic moment value.

Main technical parameters
1, the signal amplitude: 1H ≥ 100mV, signal-to-noise ratio: 40dB, 19F ≥ 10mV, signal-to-noise ratio: 26dB.
2, oscillation frequency: 18.5 MHz ~ 23 MHz adjustable, depending on the magnetic field.
3, sweep field signal: sweep field current 0 ~ 200 mA adjustable.
4, probe movement position: 0 ± 40 mm.
5, samples: water doped with copper sulfate or ferric chloride, polytetrafluoroethylene rods, etc., respectively.
6, permanent magnet: field strength of about 480mT, the relative uniformity of the magnetic field is better than 10-5, magnetic field gap: 15mm.
7, including frequency meter, the user needs to be equipped with another double trace oscilloscope.
