1 Introduction
This manual contains information about site planning and preparation prior to delivery of a
Bruker AVANCE system. The manual should be read through carefully as mistakes made
initially may be costly to remedy at a later stage.
The systems covered by this manual are AVANCE spectrometers in the range of 400-700
MHz with Ascend Aeon (actively refrigerated) magnets.
The chapters within this manual deal with various points that need to be considered for
successful system operation. They have been included to familiarize you with general
principles of successful site planning. For specific questions that may not be addressed in
this manual, or for further information on a topic, do not hesitate to contact your local Bruker
office. Please also review the Installation Questionaire at the end of the manual.
1.1 Units Used Within This Manual
The SI Unit Tesla (mT) is used throughout this manual whenever magnetic field strengths are
discussed. Some readers may however be more familiar with the Gauss (G) Unit.
For comparison the conversion fact is: 1 mT=10 G
Likewise the unit kilowatt is used for the measure of heat energy (e.g. amount of heat
generated by a device per hour). Some readers may be more familiar with these
measurements in BTU/hour:
For comparison the conversion factor is: 1 BTU/hour=0.000293 kW.
(BTU = British Thermal Unit which is the required heat to raise 1 pound of H
2
O by 1 degree
Fahrenheit).
Wherever possible both the metric and American (North and South) measure units have been
used throughout this manual. In most cases the weights and measures have been rounded
upwards where necessary. The following table offers the common metric to American
conversion factors used in this manual:
