QIC MultiStream

An integrated mass spectrometer and selector valve system for multi-component, multi-stream gas analysis

The Hiden QIC MultiStream is a complete, multi-stream gas composition monitoring system. Capable of analysing gas streams at flow rates from 4 ml/min up to 10 L/min. The system is suited to a range of applications where multi-component, multi-stream gas analysis is required, environmental monitoring for example.

A compact bench-top system for real time gas and vapour analysis


The system features Hiden’s state-of-the-art “Proteus” Multi-stream selector valve coupled with a precision, ultra-stable triple filter mass analyser. Fast data acquisition and low internal dead volume allows switching times of less than 10 seconds per stream.

An 8 way multi-stream valve module  is offered as an alternative to the Proteus valve.

Hiden’s QGA Professional quantitative gas analysis software features automatic calibration routines for accurate quantitative analysis. Gas/vapour mass spectral libraries and automatic subtraction of spectral overlaps allow for precise fragmentation pattern recording.
