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. SuperCOOL probe The SuperCOOL probe is available in two cooling methods: open type using a liquid nitrogen tank and circulating type using an air-cooled refrigerator. The open type does not require a refrigerator, so it is superior in terms of running cost. The circulating type, which has a higher cooling capacity and better sensitivity, does not require replenishment of the refrigerant and has a higher continuous operating capacity.
