The SuperCOOL probe features significantly improved sensitivity at double the sensitivity of conventional probes and thermal noise is reduced by cooling of both the detection coil and preamplifier. The SuperCOOL probe reduces measurement times to just 1/4 to enable many more samples to be measured in a single day. The SuperCOOL probe accept a 5mm diameter tube, has a wide temperature range from -40°C to +150°C , and also is suitable for polymeric samples of high viscosity.
The SuperCOOL probe (the detection coil is cooled by liquid nitrogen) is highly cost efficient when compared with the UltraCOOL probe (wherein the detection coil is cooled by liquid helium). This probe comes with a new cooling system that does not require a water chiller. As it can run experiments in 1/9 of the time, measurements which used to take several days can now be made in a few hours, thus improving the operational efficiency of the instrument.
Measurements at high temperatures of up to 150°C and the high sensitivity of the SuperCOOL probe show outstanding results for polymer samples.
Measurement time is reduced to approx. 1/9 that of a room temperature probe. A 24 hour measurement by a room temperature probe can be done in less than three hours using a SuperCOOL probe.
The above comparison of a room temperature 600MHz to a 500MHz with a SuperCOOL Probe is done using lasalocid acid. As you can see:
Note: Both data sets were collected under the same conditions for 1024 scans using a 30° pulse at a repetition rate of 2.8s. The large off-scale peaks are from acetone.
The UltraCOOL probe achieves more than 4 times the sensitivity of conventional probes while thermal noise is reduced by cooling of both the detection coil and preamplifier. Measurement times using the UltraCOOL probe are only 1/16 that of a conventional probe. What used to be an overnight measurement can now be achieved in a lunch break! The UltraCOOL probe also accepts a 5mm diameter tube, has a wide temperature range from -40°C to +150°C , and is suitable for polymeric samples of high viscosity.
Uses cryogenically cooled helium gas to achieve an ultra-low temperature with a recirculating type chiller. The coil/pre-amplifier temperature is much lower than that achieved in the SuperCOOL probe.
The SuperCOOL NMR probe is available in 2 configurations:
