Figure8.2: AVANCE Spectrometer with External Preamp (HPPR/2)
8.2 Telecommunication
Please refer to the AVANCE NEO NMR layout in chapter Floor Plan [} 79]. The following
ports/connections are required:
• Telephone/data ports behind the workstation.
• Ethernet cable between the AVANCE NEO cabinet and the workstation.
8.3 Compressed Gas
Some components of the AVANCE NEO system and the vibration isolators, which are inte-
grated into the magnet legs, operate with compressed gas.
8.3.1 General Requirements
Compressed gas line: The standard AVANCE NEO system requires one compressed gas
line with at least two regulated outputs.
Regulators: Each output should terminate with a regulator (including gage head) suited for a
pressure range of 0 - 8.6 bar (0 - 125 psi). The output of the regulator should allow the quick
connect for an 8 mm diameter gas tube.
• Compressed nitrogen gas needed for temperature control with VT experiments in order to
achieve optimal NMR performance. For example, the BCU-I cooling unit requires a dew
point of -51°C (-60°F) for the compressed gas.
• Compressed air or nitrogen gas for spinning.
• Compressed air or nitrogen gas for sample ejection, and for the magnet’s vibration isola-
tion units.
• Compressed air or nitrogen gas for the optional CryoProbe system.
