The Hiden QIC-series process gas analyzers are designed specifically for in-process gas analysis. The mass spectrometer-based QIC-series systems are suited to diverse application areas and are used routinely for thermal and thermo-gravimetric process analyses, pyrolysis and catalytic studies.
All systems feature the flexible, fast response QIC quartz-lined interface sampling directly from dynamic gaseous processes operating in the range from 50 millibar through to 2 bar, and extending up to 30 bar with the new HT-HP high-pressure interface adaptor. Multi-stream selectors enable automated sequential sampling from 1-80 gas streams.
Changes in process gas composition are measured and recorded in real time, with a response time of just 150 milliseconds and a low sample consumption rate from 1 to 20 millilitre per minute.
The interfaces operate at temperatures in the range 200C to 400C, and sample directly from in-furnace environments to 1100C with the hot-zone thermal extension.
