Supercritical-Fluid-Golden-Gate-1413x1536

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 1/16^th 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.
