Online Gas Analyzer for Aerobic Fermentation

Brand: Thmorgan
Model: HGD1200

I. Product Applications:

1. Can be integrated with 1–20 L small-scale aerobic fermenters and bioreactors to enable real-time feedback and adaptive control of fermentation process parameters;

2. Can be used in conjunction with 20–100 L pilot-scale fermenters to meet gas monitoring requirements during process scale-up.

3. Can be integrated with large fermentation tanks of 100 L or greater, providing data support for comprehensive gas monitoring throughout the entire scale-up production process;

4. It can be used for real-time monitoring and recording of the concentrations and total amounts of gases such as carbon dioxide and oxygen during fermentation.

II. Product Features:

1 , Featuring High-Precision Gas Flow Rate Control unit;

2. Equipped with a high-precision concentration monitoring unit;

3. High monitoring accuracy, enabling online measurement of gas release rates;

4. Equipped with a fully automated data acquisition and processing system;

5. Equipped with a front-mounted refrigeration dehumidification unit for efficient dehumidification and protection of the detection probe;

III. Operating Principle:

The online gas analyzer for aerobic fermentation is connected to the fermenter via a three-way valve, with a portion of the gases generated during fermentation routed to the analyzer through the gas line; the analyzer is fully automated. PLC control technology enables precise regulation of gas flow rate. The fermentation off-gas first enters a pre-cooling and dehumidification unit, where Peltier-based electronic cooling is used for condensation and moisture removal, followed by drying and filtration through silica gel and dust removal. The dried and purified gas then passes through a high-precision sensor for real-time concentration measurement. By integrating the gas’s real-time concentration, flow rate, and time, the system performs integral calculations to accurately determine the cumulative volume of fermentation off-gas. The system continuously feeds this data back to the fermenter control system, providing a basis for optimizing the fermentation process and enabling intelligent control.
