Customized design of electronic noses placed on top of air-lift bioreactors for in situ monitoring the off-gas patterns
A specially designed electronic nose was coupled to an air-lift bioreactor in order to perform on-line monitoring of released vapors. The sensor array was placed at the top of the bioreactor sensing the headspace in equilibrium with the evolving liquor at any time without the need of aspiration and...
