Optimised specifically for monitoring fast evolved-gas events, the Hiden HPR-20 TGA benchtop mass spectrometer features a state-of-the-art integrated interface and analysis system for real-time unequivocal detection of multiple gaseous species to 500 amu. The system is suited for application to diverse thermo/thermogravimetric processes and incorporates comprehensive data analysis programs for combined presentation of gas species and abundances, process temperature status and evolution rates.
The quartz/platinum internal surfaces of the QIC process interface ensure optimum sample integrity through the transfer stage to the close-coupled mass spectrometer ionisation region, minimised internal volumes enabling response times to 100 milliseconds. User-variables control transfer temperatures to 200°C and balanced flow rates down to 1A.cm3/minute, with custom adaptors providing for connection to diverse TA/TGA systems.
Routine maintenance procedures are simplified by the distinctive open architecture design, all critical sampling components being fully user replaceable. Precise temperature uniformity eliminates cold spots for long-term, trouble-free operation.
