ATR infrared spectroscopy sample holder Golden Gate

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. Key FeaturesO • 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. Specifications ATR crystal - Monolithic diamond Crystal sealing - The diamond is sealed with a metal braze into a tungsten puck. Angle of incidence - 45o Spectral range - ZnSe lenses 5000-700 cm-1 KRS-5 lenses 6500-400 cm-1 Temperature range - Ambient to 200 oC Pressure range - Ambient to 3000 psi Fittings - 1/8th Swagelok Cell material - Stainless-Steel or HastelloyFocusing optics 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.
