Important precautions, which, if not followed, may result in damage to the device itself,
are described below.
• The probe may become damaged if the data-acquisition time is too long.
• Liquid samples, samples whose volume changes (such as between the
solid and liquid states) when due to a change in temperature, and
sublimating materials cannot be measured.
Scattering the sample or bolts for the spinning cap occurs due to a change in volume
caused by the expansion of the sample. Both of these events destroy the probe.
• When you perform VT (Variable Temperature) measurement, be sure to
flow bearing gas.
If you do not flow the bearing gas, the heater produces anomalous heating then a fire
might occur inside the probe.
• When you set the measurement temperature to 150 ℃ or more, be sure
to use nitrogen gas.
If air is used, a flammable sample may ignite and fires might occur inside the probe.
Moreover, the surface of the heater that is built into the probe would oxidize and the
oxide would block a pipe, causing failure. The NMR detection coil would also
oxidize and performance of the probe would deteriorate.
• Carefully read the instruction manual then perform the magic angle
spinning.
There is a danger of destroying the probe.
• When you first adjust the magic angle, receive instructions from an
experienced person.
An incorrect adjustment might damage the probe.
