Golden Gate | High Pressure Fluids Cell

Golden Gate | High Pressure Fluids Cell

A high-temperature, high-pressure, low-volume FTIR accessory developed for the study of supercritical fluids and polymers. Based on the Golden Gate single-reflection diamond ATR accessory platform.
  • Compact reaction cell for supercritical pressures and temperatures: Its tiny 28 µl cell can be pressurised to 6000 psi and heated to 300 °C. It has 1/16th inch Swagelok fittings for in-flow of samples.
  • Robust construction: The diamond ATR element is high temperature metal bonded into a tungsten carbide disk, avoiding the use of adhesives or resins that may be dissolved or attacked by the chemical aggressiveness of supercritical fluids.

Meer informatie over Golden Gate | High Pressure Fluids Cell

The high thermal conductivity of the diamond element is ideal for fast temperature equilibrium and accurate temperature measurement, reducing analysis time and increasing sample throughput. The analyser is equipped with a thermal protection system to prevent thermal runaway.


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 300 oC
Pressure range Ambient to 6000 psi
Fittings 1/16th Swagelok

Focusing 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.
