An integrated mass spectrometer system for multi-stream fermentation off gas analysis

Measures off gas and vapour concentrations, OUR, CER, RQ  from multiple reactors

The Hiden QIC BioStream 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 including fermentation off-gas analysis, biogas production monitoring and bio-enzyme production.

Overview

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. 

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.
