Basic Equipment Set For Esr/Nmr

This basic equipment set is intended for investigating the electron spin resonance (ESR) of an unpaired electron of a DPPH sample as well as the nuclear magnetic resonance (NMR) of glycerin, teflon and polystyrene. Resonances are observed via transitions induced through high frequencies resulting from changes in the external magnetic field. Resonance absorption curves can be represented with an oscilloscope, XY recorder or interface.
The equipment set consists of a control panel for ESR/NMR, basic unit for ESR/NMR and a pair of coils.
Experiment descriptions are included.

The control panel for ESR/NMR provides all the required supply voltages and high frequencies, and amplifies and processes the signals needed for observation of the results.

Analog input: BNC jack for connecting the ESR/NMR sample heads
Outputs:

  • Sweep generator: Coil current of 0 to 250 mA, 20 Hz via a multiple cable
  • Fast: Voltage signals of 0 to 1 V proportional to the coil current and resonance signal for oscilloscopic observations via 4-mm-jacks
  • Slow: Voltage signals of 0 to 1 V proportional to the coil current and resonance signal for recording data with an XY recorder or interface via 4-mm-jacks
Frequencies: For ESR – MID, HI, LO
(approx. 45 MHz, 60 MHz, 75 MHz)
for NMR (approx. 13 MHz) via a multiple jack
Digital output: BNC jack for frequency measurement, 1:1000 scaling
Dimensions: 170 mm x 105 mm x 45 mm
Weight: 0.4 kg

The basic unit for ESR/NMR is intended for mounting the sample heads (from U18850 or U18902), coils and permanent magnet (from U18902). It includes an integrated power source for supplying the coil pair and acoustic signal generator whose loudness is proportional to the intensity of the resonance signal. The basic unit is controlled via the control panel for ESR/NMR.

Power source: 0 to 250 mA
Dimensions: 165 mm x 105 mm x 135 mm
Weight: 1.25 kg

The coil pair is used to generate the variable magnetic field for electron spin resonance and – in conjunction with the permanent magnet (from U18902) – nuclear spin resonance.

Magnetic flux density: 0 to 3.67 mT
Dimensions: 20 mm x 74 mm Ø
Weight: 0.2 kg each
