CO2/O2 Gas Analyzer

Solida Biotech Gas Analyzer

 

The CO2 / O2 gas sensor analyses the amount of oxygen uptake and carbon dioxide production in the outlet gas from your bioreactor or fermenter. Real-time monitoring of CO2 and O2 is a valuable tool for the measurement of cell growth within your fermenter vessels. Monitoring these changes can improve productivity by indicating the correct rates for oxygen flow and substrate feed. Using our gas analyser you can also calculate respiratory quotient (RQ), oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR), and metabolic rate.

SOLIDA infrared gas analysers can be used to simultaneously measure the concentration of CH4 and H2 in sample gases. This is based on the single source two beams non dispersion infrared (NDIR) method for CH4, CO2, and the fuel cell method (ECD) for H2S and O2.
The general applications are landfill, anaerobic digestion and other fermentation processes.

Our package can include some or all of the following.
