WebApr 7, 2009 · EPR spectra of samples containing 10% glycerol were recorded at 15 K on a multipurpose Bruker E680 spectrometer equipped with an Oxford CF935 helium cryostat and EN4118X-MD-4-W1 probe head (≈9.73 GHz). Redox potentials were measured by square wave voltammetry at 4 °C in 50 mM potassium phosphate (pH 7.4), as previously … WebThe Oxford-CF935 liquid helium cryostat allows for EPR at pumped helium temperatures (down to ~1.4 K). Capable of ESEEM, HYSCORE, ENDOR, and EDNMR techniques. 263 (263 GHz) Capable of performing CW and pulse EPR techniques 263 GHz. Currently equipped with a ~ 200 mW microwave amplification system similar to our D-band instrument.
