Multi-Component, Multi-Stream Gas Analysis with the QIC Multistream

The QIC MultiStream from Hiden Analytical is a complete, multi-stream gas composition tracking system.

The system can analyze gas streams at flow rates from 4 mL/minute up to 10 L/minute. It is well-suited for a variety of applications that require multi-component, multi-stream gas analysis, for example, environmental monitoring.

The QIC MultiStream system features Hiden Analytical’s advanced 'Proteus' Multi-stream selector valve together with an accurate, ultra-stable triple filter mass analyzer. The combination of low internal dead volume and rapid data acquisition enables switching times of less than 10 seconds for every stream.

An 8-way multi-stream valve module is also provided as a substitute for the Proteus valve.

The QGA Professional quantitative gas analysis software from Hiden Analytical features automatic calibration routines to enable precise quantitative analysis. Gas or vapor mass spectral libraries and automatic subtraction of spectral overlaps enable users to precisely record fragmentation patterns.
