Studying Polymers and Supercritical Fluids with a Low Volume FTIR Accessory

The analysis of polymers and supercritical fluids is possible using the Supercritical Fluid analysis model of the Golden Gate^TM ATR System. The Supercritical Fluid model has a small volume and is robust, allowing high pressures and temperatures to be achieved.

Golden Gate^TM ATR System

The ATR of the system, like the conventional Golden Gate^TM, uses a diamond surface that is high-temperature bonded into tungsten carbide. The bonding does not use sensitive resins or adhesives, which could be broken down by highly reactive supercritical fluids.

The sample chamber of the system has been built to withstand high temperatures (up to 300 °C) and high pressures (up to 6000 psi). In addition, the system is thermally protected to prevent (potentially dangerous) thermal runaway.

The diamond ATR surface is thermally conductive, meaning the temperature equilibrates quickly during measurement, providing accurate results without the need to wait for equilibration to happen. This saves precious time and increases measurement throughput.

Supercritical Analysis Model

The system is perfectly designed for the analysis of polymers under extreme conditions and for fluids in supercritical (or near supercritical) states. Additionally, the Supercritical Analysis model can be used to measure other materials at high temperatures and high pressures.
