BioPAT® Xgas

As all living things use O₂ and produce CO₂ the total activity of your cells can be understood from how they are respiring. Therefore, using the combination of a Sartorius Stedim Biostat® bioreactor with mass flow controllers and integrated BioPAT® Xgas you can accurately measure the rate of O₂ uptake (OUR), CO₂ production rate (CPR) and calculate automatically the respiration coefficient (RQ) of your process. These calculations are performed by BioPAT® MFCS which accounts for the dynamic parameter changes of your process conditions. The sensor itself automatically compensates for pressure and humidity so there is no need to have heated exhaust lines. The BioPAT® Xgas fermenter package offers you a powerful process development tool which can reduce your process optimization time by giving clearer online understanding of your cells metabolic activates. Further, with accumulative O₂ uptake or CO₂ production, automated control loops can be established using BioPAT® MFCS S88 recipes which guide your process on a tighter processing pathway giving higher consistency. The BioPAT® Xgas capability of detecting small changes in the percentage of O₂ and CO₂ offer the ability to detect a fault in dissolved O₂ probes and analyze the efficiency of CO₂ stripping. As all of these items come integrated from Sartorius Stedim Biotech they are all tested and covered by our Extend® service coverage.
