10 CryoProbe and Other
Accessories
The CryoProbe accessory for the AVANCE NEO NMR Spectrometers offers dramatic in-
creases in signal to noise ratio (S/N) by reducing the operating temperature of the NMR coil
assembly and the preamplifier.
The CryoProbe accessory consists of two major components: the CryoProbe and the Cry-
oPlatform. The CryoProbe is similar to a standard probe, however contains cryogenically
cooled RF coil and electronics. The CryoPlatform, which provides cryogenic cooling for the
CryoProbe, is made up of:
• CryoCooling Unit with control electronics.
• Helium Compressor (along with any associated cooling equipment).
• Helium Gas Cylinder (for purging of the CryoProbe).
• Helium transfer lines and transfer line support.
The CryoCooling Unit must be sited adjacent to the magnet, whereas the Helium Compressor
and Helium Gas Cylinder may be sited remotely. The first step in the site planning involves
review of the magnet area to determine if floor space is available to accommodate the Cry-
oCooling Unit. The CryoCooling Unit is optimally located level with the magnet. Other config-
urations, such as magnet pits that can not accommodate the CryoCooling Unit, require spe-
cial consideration.
