OGA – Off Gas Analyzer

With integrated true mass flow measurements, the OGA platform will allow you to monitor real-time metabolism in your aerobic and microaerobic fermentations, cell cultures, plant and animal studies. Your bioreactor may be 50 mL, 200 kL, or anything between!

OGA system offers a way to continuously monitor and record a variety of metabolic parameters like OUR, CER, RQ in real time. Totalization readouts provide total metabolic numbers with a button press. Plug-and play operation via an intuitive GUI that is available on any web-enabled device such as a smart phone, tablet or a computer.

Off Gas Analyzer Applications

  • Bioprocesses: fermentation, cell culture, immobilized and supported cell cultures, solid state fermentations
  • Animal, plant and tissue metabolic studies
  • Yeast quality/vitality measurements in bakery and brewery processes (pitching yeast, propagators and brinks).
  • Aerobic, anaerobic, and micro-aerobic processes
  • Robust and optimal control of bread proofing processes in large and small bakeries to improve production efficiency and lower costs,
  • Estimate biomass growth non-invasively even in complex heterogeneous media
  • In situ/in-process mass transfer efficiency (kLa) measurements

OGA System Features:

  • Infrared CO2 measurement (four standard ranges: 0-40,000ppm, 0-10%, 0-30%)
  • Electrochemical O2 measurement (0-100%)
  • True molar/mass flow measurement (infinite range)
  • Automatic process inlet gas sampling and analyses option
  • Three fully programmable, assignable analog signal outputs (4-20mA)
  • Modbus/TCP for full industrial automation compatibility
  • Gas temperature, and various computed metabolic paramaters (OUR, CER, RQ, Totals)
  • Plug & play operation
  • Intuitive Graphical User Interface (GUI) available on any wifi enabled device
  • Optional local touchscreen GUI (OGA) or remote GUI only (µOGA)

µOGA (Micro OGA) has all the same features as the OGA without a local display! You can use a remote GUI and have access to the same great functionality as the OGA system!

 

FAQs

1. What is an Off Gas Analyzer?

The QuantiPerm OGA system is an off gas analyzer platform that takes a gas stream from a bioreactor, plant or an animal experimental system and analyzes the composition and gas flow rates in real time.

2. What are the typical applications for Quantiperm’s Off Gas Analyzer?

Typical systems find applications in various types of microbial and yeast fermentations, cell cultures, various bioreactor systems, animal metabolism studies, greenhouses, etc.

3. How does OGA improve bioprocess efficiency and control? 

The system is intended for metabolic monitoring of a single bioreactor, animal cage or a test chamber, or any similar process. The OGA system not only reports instantaneous exhaust gas total flow, O2 and CO2 composition, but also calculates and reports in real-time several critical metabolic parameters such as the oxygen uptake rate (OUR, mL min-1 L-1), carbon dioxide evolution rate (CER, mL min-1 L-1), respiratory quotient (RQ = CER/OUR), as well as the cumulative total gas volume used (v/v) and total metabolic uptake of oxygen (v/v) and carbon dioxide (v/v) at any given time continuously.
