Probe Safety Considerations

BRUKER probes are designed to hold the sample, transmit radio frequency signals which
excite the sample and receive the emitted response. The transmission and reception is
achieved by using specially designed RF coils.

The  probe  is  inserted  into  the  bottom  of  the  magnet  and  sits  inside  the  room  temperature
shims.  Coaxial  cables  carry  the  excitation  signals  from  the  console  amplifiers  to  the  probe
and the NMR signal back from the sample to the receiver. The cables are routed through a
set  of  preamplifiers  (the  HPPR)  which  are  situated  next  to  the  base  of  the  magnet.  The
preamplifiers are needed to boost the NMR signals which are typically very weak.

5.1

Personnel Safety Issues

All persons who work with or in the close vicinity of an NMR system must be informed about
its safety issues and emergency procedures.

If in doubt: Wear goggles and protective gloves, particularly when handling samples!

Inherent Safety

An NMR system, including its components, is designed for inherent safety. Pressure relief
valves, sensors, and error handling in hardware and software have been included to protect
the operator, equipment, and environment.

Technically Qualified Personnel Only

Only persons with a basic technical understanding of electricity, pressurized gas systems,
and cryogens should operate and maintain an NMR system. User interface, system
messages, and manuals require a good understanding of the English language.

No User-serviceable Parts Inside

There are no user-serviceable parts inside a probe/CryoProbe. Do not open these devices.

Magnetic Stray Field

When working within the 0.5 mT (5 Gauss) stray field of the magnet, all magnetic parts and
tools must be avoided or handled with great care.

CAUTION: Deposit mechanical watches and cards with a magnetic strip (e.g. credit cards)
outside the 0.5 mT (5 Gauss) range of the magnet.
