For direct information on gas uptake and for dissolved output rates
Hiden’s gas analyzers are configured with a multiport Off-Gas analysis manifold enabling simultaneous sampling from multiple fermentors.
The Off-Gas measurement provides the respiratory quotient in a time and space averaged form and with good response time. By comparison data from multiple dissolved species probes are more specific and can provide information about stirring efficiency, aeration and feed distribution within the fermentor/bioreactor. Dissolved gas measurements have the advantage of giving direct information on gas uptake and for dissolved output rates.
Hiden Analytical offers systems with either Off-Gas or dissolved species inlets or both.
