2 Introduction
2.1 AVANCE NMR Spectrometer Intended Use
The Bruker AVANCE systems should only be used for their intended purpose as described in
their respective manuals and outlined in this section.
Use of the unit for any purpose other than that for which it is intended is taken only at the
users own risk and invalidates any and all manufacturer warranties. Service or maintenance
work on the consoles must be carried out by qualified personnel. Only those persons
schooled in the operation of Bruker spectrometers should operate the unit.
The Bruker AVANCE systems are ultra high precision spectrometers for the analysis of
chemical structures and molecular properties. Small liquid or solid samples are placed into an
extremely strong magnetic field. They are irradiated with short radio frequency pulses and the
resulting weak transient radio frequencies emitted thereafter by the magnetically active nuclei
(of selected chemical elements) of the samples are then observed. The instrumental
technique is called Nuclear Magnetic Resonance spectroscopy (NMR).
AVANCE spectrometers are available with vertical bore magnets of field strength between 7T
to over 20T with room temperature bore sizes between 54 mm and 155 mm. Typical sample
amounts range from nanogram to less than gram level.
The method allows to identify and/or confirm the structure of chemical and biochemical
compounds and mixtures including information concerning molecular mobility and
interactions.
The method is also used to obtain information about the distribution of magnetically active
nuclei within a sample (NMR Imaging, NMR Microscopy).
Typical applications of NMR spectrometers are in all areas of academic and industrial
research and quality control in the fields of materials science, organic chemistry, inorganic
chemistry, and in the analysis of biological samples.
The AVANCE spectrometer line can be equipped/connected with a large variety of optional
accessories such as:
• Variable temperature control
• Pneumatic control to enable fast sample rotation
• Variable magnetic field gradients
• Flow-Through and HPLC equipment and according accessories
• Automatic sample changers
• Automatic sample preparation
• Special ultra low temperature probes (CryoProbes and their accessories)
AVANCE spectrometers are not designed primarily for:
• Investigations of ferromagnetic materials.
Avance Spectrometers are not approved for diagnostic purposes in the medical field such as
IVD according to legal requirements.

Introduction
8 Z31836_5_005
2.2 Purpose of this Manual
The purpose of this manual is to summarize the safety considerations which apply to the
Avance system. It does not replace the individual manuals but is meant as a quick and easy
access to the relevant information concerning safety issues. As such, one copy should
always be available at the operator's desk. Please, take care that each operator of the
system is aware of the importance of this manual. In addition, each operator is advised to
read the manual in order to be aware of any safety risks which may be related to the use of
the AVANCE system.
2.3 Magnetic Safety
In terms of safety the presence of a relatively strong magnet is what differentiates NMR
spectrometers from most other laboratory equipment. When designing an NMR laboratory, or
training personnel who will work in or around the laboratory, no other feature is of greater
significance. As long as correct procedures are adhered to, working in the vicinity of
superconducting magnets is completely safe and has no known harmful medical side effects.
Negligence however can result in serious accidents. It is important that people working in the
vicinity of the magnet fully understand the potential hazards.
Of critical importance is that people fitted with cardiac pacemakers or metallic
implants should never be allowed near the magnet.
A magnetic field surrounds the magnet in all directions. This field (known as the stray field) is
invisible and hence the need to post warning signs at appropriate locations. Objects made of
ferromagnetic materials, e.g. iron, steel etc. will be attracted to the magnet. If a ferromagnetic
object is brought too close, it may suddenly be drawn into the magnet with surprising force.
This may damage the magnet, or cause personal injury to anybody in the way!
Because the strength of the stray field drops significantly as one moves away from the
magnet, it is useful to discuss safety in terms of two broadly defined regions, the inner and
outer zone. In terms of organizing a laboratory as well as defining good work practices, the
concept of an inner and outer zone is particularly useful.
The physical extent of these two zones will depend on the size of the magnet. The bigger the
magnet, the stronger the stray magnetic fields and hence the larger the extent of the two
zones. Details of stray fields for various magnets can be found in the Site Planning Guides
delivered with the BASH DVD.
2.3.1 Safety Precautions within the Inner Zone
The inner zone extends from the magnet center to the 1 mT (10 Gauss) line. Within this
region objects may suddenly be drawn towards the magnet center. The attractive force of the
magnet can change from barely noticeable to uncontrollable within a very short distance.
Under no circumstances should heavy ferromagnetic objects be located or moved within this
zone.
Any ladders used when working on the magnet should be made of non-magnetic material
such as aluminum. Helium and nitrogen dewars which are used to top up the liquid levels
inside the magnet must be made of non-magnetic material.
Do not allow small steel objects (screwdrivers, bolts etc.) to lie on the floor near the magnet.
These could cause serious damage if drawn into the magnet bore, especially when no probe
is inserted in the magnet.
Mechanical watches may be damaged if worn within the inner zone. Digital watches can be
worn safely. Of course, the precautions for the outer zone which will now be discussed must
also be adhered to within the inner zone.

Introduction
Z31836_5_005 9
2.3.2 Safety precautions within the outer zone
The outer zone extends from the 1mT (10 Gauss) line to the 0.3 mT (3 Gauss) line. The
magnet's stray field does not get blocked by walls, floors or ceilings and the outer zone may
well encompass adjoining rooms. The stray field may erase information stored on magnetic
tapes or discs. Bank cards, security passes or any devices containing a magnetic strip may
be damaged. CD/DVD’s will not be damaged, although CD/DVD drives may contain magnetic
parts. When using pressurized gas cylinders made of steel, they should be located well
beyond the outer zone (preferably outside the magnet room) and must always be properly
fixed to the wall. The color display of computer monitors may suffer some distortion when
located too close to the magnet, although permanent damage is unlikely. Once beyond the
outer zone any special precautions on account of the magnet stray field are no longer
necessary.
2.4 Cryogenic Safety
The magnet contains relatively large quantities of liquid helium and nitrogen. These liquids,
referred to as cryogens, serve to keep the magnet core at a very low temperature.
Because of the very low temperatures involved, gloves, a long sleeved shirt or lab coat and
safety goggles should always be worn when handling cryogens. Direct contact with these
liquids can cause frostbite. The system manager should regularly check and make sure that
evaporating gases are free to escape from the magnet, i.e. the release valves must not be
blocked. Do not attempt to refill the magnet with helium or nitrogen unless you have been
trained in the correct procedure.
Helium and nitrogen are non-toxic gases. However, because of a possible magnet quench,
whereupon the room may suddenly fill with evaporated gases, adequate ventilation must
always be provided.
2.5 Electrical Safety
The spectrometer hardware is no more or less hazardous than any typical electronic or
pneumatic hardware and should be treated accordingly. Do not remove any of the protective
panels or grounding measures from the various units. They are fitted to protect you and
should be opened by qualified service personnel only. The main panel at the rear of the
console is designed to be removed using two quick release screws, but again, this should
only be done by trained personnel. Please note that, unless disconnected, cooling fans on
the rear panel will continue to run even with the panel removed.
Before maintenance, repair or shipment, the system and/or its components must be
completely switched off and unplugged or disconnected and dismounted from the rack. Refer
to the individual component manuals for specific information.
2.6 Chemical Safety
Users should be fully aware of any hazards associated with the samples they are working
with. Organic compounds may be highly flammable, corrosive, carcinogenic etc.

Introduction

3.1 General Safety Instructions
The spectrometer system user should check the equipment at regular intervals for any
damage or wear and inform service immediately of any abnormality.
Do no use the equipment and inform the service staff, if you are in doubt about the correct
state of any component!
In the unlikely case of one of the following, stop using the equipment, interrupt the current
supply, disclose this circumstance to the service staff and ask for instructions:
• The power cord, power plug or power supply are cracked, brittle or damaged.
• Signs of excessive heat appear.
• There is evidence or suspicion that a liquid has intruded into any enclosure.
• The power cord or the power supply have been in contact with any liquid.
• The unit/components has been dropped or damaged in any way.
3.2 System Grounding and Potential Equalization of Avance
Systems
In order to ensure a safe handling of the spectrometer under any condition, AVANCE
systems must be part of the general potential equalization at the user's site.
To establish a complete potential equalization of the whole system, each system is delivered
with grounding cables that have to be attached to the console, the HPPR and the magnet as
follows:
• A cable must be connected from the central grounding point located on the lower backside
of the cabinet, to the grounding of the building.
• When an external preamplifier (HPPR/2) is used, a cable has to be connected from the
central grounding point of the spectrometer to the grounding point of the external
preamplifier base plate (second figure below).
• A cable must be connected from the magnet grounding point to the grounding point of the
spectrometer (first figure below), or if an external preamplifier is used, to the grounding
point of the external preamplifier (second figure below).
Please note that the grounding cables must be in place and tightly connected to the
respective grounding points before the AVANCE system is energized or connected to the
mains connector. Disconnecting one of the cables is only allowed after the whole system has
been switched off.
The customer must be advised by the service engineer to take note of the safety information
in this manual. A confirmation that they have been instructed to do so is part of the
Acceptance Protocol.

WARNING: Installation and servicing should only be done by BRUKER qualified personnel.
Always disconnect power cable before servicing. Under certain conditions dangerous
voltages may exist even with the power cable removed. To avoid injuries, always disconnect
power and discharge circuits before touching them.
NOTE: Operating personnel must not remove chassis covers except as described in this
manual. Do not replace AQS units with mains switch turned on. User interface, system
messages, and manuals require a good understanding of the English language.

Cabinet Safety
Z31836_5_005 17
Electrical Safety
The AQS systems’s degree of protection against electrical hazard complies with IEC IP20,
i.e. all electrical parts are protected against touching.
WARNING: All electrical connectors must be used as supplied by BRUKER. Do not substitute
them by other types.
Lifting the AQS Chassis
WARNING: At least two people are needed to insert and remove the AQS chassis from the
electronics cabinet. A fully equipped AQS system can weight in excess of 50kg.
NOTE: Remove some or all of the AQS units from the chassis prior to handling to reduce
weight.
Cleaning
WARNING: Always switch power off and disconnect the power cable before cleaning. Never
power on until all surfaces are completely dry.
Clean the outside of the AQS chassis and units with a soft, lint-free cloth dampened in water.
Do not use any detergent or other cleaning solvents.
3.4.3 Safety Stop
If the temperature inside the mainframe exceeds the absolute maximum limit of save
operation, the mains supply to the chassis is switched off automatically (and without warning)
to prevent permanent damage to the AQS units. This „Safety Stop“ condition is indicated with
a red lamp on the front panel as long as the mains supply is present at the power connector.
Make sure to establish and remove the cause of the Safety Stop condition before you use the
spectrometer again.
The Safety Stop can be caused by a fan or power supply failure within the mainframe. Other
causes can be inefficient cooling air supply to the mainframe or exceeding ambient air
temperatures within or around the spectrometer cabinet.
Contact Bruker service if you cannot establish the cause of the failure. The chassis can be
returned to its normal working state by switching the mains circuit breaker manually OFF and
ON. An AC power loss also resets the chassis to its working state
3.5 BSMS/2
The enhanced BSMS/2 system contains a set of highly integrated boards (ELCB and
SCB20), which provide optimal performance, higher resolution and increased stability. The
BSMS/2 mainframe is designed as a subunit in the electronics cabinet of the NMR
Spectrometer. For the environmental conditions please refer to the site planning guide of the
spectrometer system.
The following general safety precautions must be observed during all phases of operation
and service of the BSMS/2 system. Failure to comply with these precautions or with specific
warnings elsewhere in this manual violates safety standards of design, manufacture and
intended use of the BSMS/2 system.
BRUKER assumes no liability for the customer‘s failure to comply with these requirements
