People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon ...
Anders als bei elektrochemischen in-line CO2-Sensoren basiert die CO2-Messung des Solid-State-Sensors auf einem optischen Prinzip.

· Sensors can be connected to disposable bioreactors in three ways. Single-use, sterilizable sensors can be interfaced as in-situ sensors into the disposable bioreactor during its production process, prior to the final sterilization step, and used only once, together with the reactor. In general, only inexpensive sensors will be used in this way.
Flow-through cells with integrated CO 2 sensor even allow perfusion monitoring in bioreactor bypasses. Our optical CO 2 measurement devices are suited for culture monitoring applications from microliter- up to production-scale.
*Remark. Pressure sensors are installed at the bottom of the vessel and on the top lid for overpressure control (optionally) and for indicative volume/level measurement In customized versions several optional sensors are available: Optical Density. pCO2. Other on request. O2/CO2 gas analyzer. Methanol sensor
Optical sensors can be easily miniaturized and due to their small size they can even be applied e. g. in small-scale stirred bioreactors, without disturbing the culture environment or liquid flow. Furthermore, these sensors do not require reference cells and do not consume the analyte during measurement. One of the greatest advantages of optical sensors, however, is the possibility of remote ...

cell cultures in flasks or dishes are usually placed in CO2 incubators. In bioreactors, the principle is the same; CO 2 is introduced to the culture from a compressed gas cylinder. In bioreactors, the medium pH is continuously measured using a pH sensor and CO 2 is added as needed. This is different from the situation in a CO 2 incubator, in which the CO 2 concentration in the internal ...
