Golden Gate In-situ Reaction Cell ATR

The Golden Gate in-situ reaction cell allows in compartment reaction monitoring over a broad range of extreme conditions.



Golden Gate | In-situ Reaction Cell ATR

The In-Situ Reaction Cell for the Golden Gate ATR is used for monitoring processes in a heated and pressurised reactor by single-reflection ATR spectroscopy. A stirring mechanism is an optional add-on.


  • Pressurised reaction cell: The 24 ml cell can be pressurised to 3000 psi and heated to 200 °C. It features a cooling jacket and has 1/8th inch Swagelok fittings for in-flow of reactants.
  • Resistant materials: The In-Situ reaction chamber can be manufactured from Stainless-Steel or Haselloy, depending on the application. The monolithic diamond ATR crystal is robust and chemically resistant.
  • Optional stirring device: A motorised variable speed stirrer with sapphire shaft and integrated pressure cap is available as an option.

The Golden Gate uses focusing lenses to achieve a tightly focused beam on the diamond ATR crystal. The standard lens material is ZnSe but KRS-5 lenses are also available as an option where access to the lower wavenumber region of the spectrum is required.
