Optical CO2 Sensors

Our optical CO 2 sensors measure the partial pressure of carbon dioxide (pCO 2) in are optimized for culture media and physiological solutions, and can be used for applications from micro to macroscale. You can choose from different CO 2 sensor designs to get a dissolved CO 2 probe that really fits your requirements.. Read more


Dissolved CO2 Measurement in Cell Culture: Integrating ...

Mar 04, 2021· Dissolved CO2 Measurement in Cell Culture: Integrating an Inline CO2 Sensor. It has become industry practice to keep a close watch and refined control on pH and dissolved O2, in conjunction with parameters including pressure, temperature, and aeration rates. We’ve also seen a growing necessity to monitor CO2 gas levels within process cultures ...

Typical Applications s In situ measurement of dissolved CO2 s Monitor fermentation s Analyze cell culture processes s Observe metabolism changes systems accessories Fully Autoclavable, Fits Into Most Bioreactors This rugged sensor is a disposable, autoclavable capsule that …


Detection of dissolved CO2 gas using an opencircuit resonator

The resonant frequency measured by the antenna was shown to vary significantly with the amount of CO2 dissolved in the water, demonstrating the sensor''s capability for detecting the dissolved gas. These findings encourage further testing for using this antenna to detect CO2 dissolved in blood or a blood analogue and demonstrate potential for ...


TECHNICAL NOTE : Dissolved CO2 and Units of Measurement

various units of measure for CO2 in water, as well as, how to convert between these units. This will allow the user to correctly measure and report data using dissolved CO2 sensors, including the CO2Pro Series and Mini CO2 sensors manufactured by ProOceanus Systems. Figure 1. Dissolved CO2 sensor with membrane equilibrator.


Dissolved CO2 Sensors | Products Suppliers | Engineering360

Even though dissolved CO2 sensors are commercially available, , from YSI Inc., (Yellow Springs, OH) or Metler Toledo (Columbus, OH), dissolved CO2 is still measured using offline blood gas analyzers such as those from Nova Biomedical (Waltham, MA).


How Do Electrochemical Sensors Work? Analytical ...

Aug 26, 2019· Gas finds its way into the outlet of the membrane on top of the sensor housing. Once the gas reaches the working electrode, an electrochemical reaction occurs. This reaction is either an oxidation or a reduction, depending on the type of gas. (For example, carbon monoxide gets oxidized into carbon dioxide, and oxygen gets reduced to water).


NonSeveringhaus potentiometric dissolved CO2 sensor …

When used together with a traditional reference electrode, the sensor system is confirmed to also monitor sample pH and carbonate along with carbon dioxide. A selectivity analysis suggests that Cl() does not interfere even at high concentrations, allowing one to explore this type of sensor probe for use in seawater or undiluted blood samples.


Parameters that reflect the carbon dioxide content of blood

Total carbon dioxide blood content is the sum of these four components. Within the microvasculature of the lungs (FIGURE 1b) the partial pressure gradient across the alveolar membrane determines that dissolved CO 2 passes from blood to alveoli. This loss of carbon dioxide from blood favors reversal of the red cell reactions described above.


Physiology, Carbon Dioxide Retention StatPearls NCBI ...

Jan 04, 2021· In the human body, carbon dioxide is formed intracellularly as a byproduct of metabolism. CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation. CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of hemoglobin for oxygen (O2). Fluctuations in CO2 levels are highly …
