Extremely High Sensitivity Cryogenic Probe, UltraCOOL Probe

  • Summary


We successfully developed UltraCOOL probe that enables reduction of thermal noise and achieves extremely high sensitivity by keeping the detection coil and pre-amplifier of probe at a very low temperature. This probe makes it possible to reduce the measurement time of 13C NMR to 1/25, compared to conventional room temperature probes.

UltraCOOL Probe features

  • High sensitivity has been achieved!
    1H sensitivity is 4 times and, 13C sensitivity is 5 times higher than conventional room temperature probes.
  • Auto-tuning and a built-in FG Coil are available, which makes it possible to perform the same measurements as a normal probe!
  • Capable of long time high temperature measurements, and is extremely effective in analysis of polymer’s stereoregularity and so on!
