DASGIP® GA for Exhaust Analysis

DASGIP® GA for Exhaust Analysis

Through online exhaust monitoring researchers gain valuable insights into critical culture parameters such as biomass development, substrate consumption and product formation. Eppendorf DASGIP GA exhaust analyzers offer most accurate data and automatic calculation of oxygen and carbon dioxide transfer rates (OTR, CTR) and respiratory quotient as well as feedback control.

Product Information

The DASGIP GA4 exhaust analyzer supports precise online measurement of exhaust oxygen and carbon dioxide in four discrete analyzer channels. Systems of up to sixteen bioreactors can be monitored. An integrated mass flow sensor allows online calculation and monitoring of oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR) and respiratory quotient (RQ), permitting direct conclusions on the metabolic state of the culture and online feedback loops. Optionally the DASGIP GA4 can be equipped with an analog input/output interface for easy integration into 3rd party systems.

Features

  • Online calculation of OTR, CTR and RQ allowing for direct feedback
  • Available with two alternative electrochemical O2 sensors to best serve individual customer's needs (1 – 50 % O2 or 0 – 100 % O2)
  • Can be operated as a stand-alone solution with EasyAccess Software
  • Humidity and temperature compensation (rHT option)
