  • In situ cell assembly kit - accessories kit comprising 30+ parts for the assembly of plastic cell capsules and other in situ cells, e.g. pouch/plastic bag cells
  • Cu- and Al-wire current collectors
  • Cu- and Al-mesh current collectors
  • PTFE tubes for in situ cells with flow option
  • Spacer disc materials: Teflon (0.25/0.50 mm), Viton rubber (0.5/1.0 mm)
  • Three-ports in situ setup for static NMR/MRI probes
  • Three-way in situ cell adapter
  • BioLogic SP-50e, SP-150e, and 200 potentiostats with/out EIS and various options on the cell cable lengths
  • Virtual and on-site installation and user training sessions on in situ NMR Consulting

eCAT - in situ NMR/e-chem data analysis tool

Our tool "eCAT" allows automatic e-chem/NMR (raw) data processing and visualisation. The raw data input, e.g. Bruker Topspin NMR and BioLogic EC-Lab data is combined in one plot with individual NMR raw data handling such as baseline and phase correction for each spectrum. Postprocessing of the data including the peak fitting and the creation of videos is optional.

REDOR Box

Our REDOR Box splits a single X-channel (e.g. of a Bruker H—X MAS probe) into a double-resonance circuit to enable X—Y Rotational Echo Double Resonance (REDOR) and similiar NMR experiments.

Options:

  • Large REDOR Box: fields of 200 - 600 MHz
  • Small REDOR Box: fields of 700 - 900 MHz

Specifications:

  • Up to 1000 W RF pulse power (50 μs)
  • VSWR < 1.2
  • Frequency splitting 1 - 20 MHz, e.g. 13C/23Na, 13C/27Al
  • Larger frequency splitting is subject to discussion
  • Suitable for Bruker 4.0 and 3.2 mm H—X(—Y) MAS probes (X channel)
  • Suitable for DNP experiments
  • Suitability for other MAS rotor/probe sizes is subject to discussion
  • The box is not suited for the 1H/19F channel
  • The H channel can be used with the REDOR Box attached to X
  • The Y channel can still be used with the REDOR Box attached to X
  • Simple installation/mounting directly at the probe
  • N-type connectors
  • Efficiency of up to 80% compared to single resonance probe
