Product Description:
  • New Auto-tuning that has better reproducibility and shorter tuning time.
  • Fully flexible sequential measurements including randomized values of parameters, e.g. sample temperature, microwave power, etc.
  • A foot operated trigger (option) to start data measurement can be used to minimize dead time after reagents are mixed to generate short lived radicals.
Major New Functions
  • Easy-to-use operation interface under Windows10™
  • Hands-free measurement start using foot switch.
  • Both progressive and randomized settings of sequential measurement parameters possible.
  • Improved display of multi-dimensional data.
  • Batch processing of sequentially measured data, including background subtraction.
Major Features
  • For measuring radicals generated by photo-irradiation, the standard universal cavity has an optical irradiation window which has high transmittance.
  • High stability Auto-tuning.
  • Each attachment easy to attach and detach.
