The importance of identification and measurement of the gases evolved and consumed in thermal reaction studies is increasingly recognised as a critical element in the performance quantification of a very wide range of materials engineered for thermal processing.
The new Hiden QGA mass spectrometer evolved to address the need for a fast-response, multirole gas analysis system readily adaptable to monitor and/or control a diverse range of thermal reaction systems and processes.
Typical application areas include reaction kinetics, catalyst characterisation, thermo-gravimetric studies and temperature programmed desorption, reduction and oxidation. The system measures all gas and vapour species with molecular weights up to 300 amu and includes external inputs enabling integration and display of process parameters such as temperature, weight and pressure with the measurements. A family of dedicated process interfaces, together with a custom design service for specialised applications, provide direct and optimised coupling to the majority of process systems.
System operation, calibration, data acquisition and display are fully automated with full manual control selectable when required for the researcher. For multistream applications the expanded range of inlet systems enable monitoring of from 4 up to 80 gas streams automatically and sequentially in any userselected sequence.
