The detection coil and preamplifier are cooled to cryogenic temperature to reduce thermal noise to an extremely low level, enabling measurement with sensitivity several times higher than that of conventional room temperature probes. Automatic tuning and matching is supported, so a wide variety of continuous measurements can be performed in combination with the auto-tuning unit.
JEOL offers three types of cryogenic probes for solution NMR:
・UC: UltraCOOL probe
・SCO: SuperCOOL Open type
・SCC: SuperCOOL Closed type
All probes are capable of controlling the sample temperature over a very wide range from -40°C to +150°C. The Probe Lifter and Probe Arm are available as optional accessories to alleviate probe exchange.
UltraCOOL probe
The UltraCOOL probe is capable of ultra-sensitive measurement, which is a feature of cryogenic probes, as well as stable high-temperature measurement, which is necessary for analysis of polymers and other materials. It also supports the new high-speed automatic tuning and matching.
