A Planar pCO2 Sensor with Enhanced Electrochemical ...

· To develop planar microchemical pCO2 sensing devices with improved electrochemical properties, we combined two advanced technologies. One is a differential sensor arrangement to simplify the microfabrication procedure by employing pH-sensitive gas-permeable membranes, and the other is the use of an enzyme (carbonic anhydrase) to shorten total measurement time by accelerating the …

Development of Neutral Red as a pH/pCO2 Luminescent Sensor ...

Future studies will evaluate the feasibility of NR as an intracellular in vivo pCO2 sensor in aquatic organisms critically impacted by increasing global CO2 levels. Neutral Red (NR), a eurhodin dye, is often used for staining living cells, but we demonstrated for the first time that NR can also serve as a CO2 sensor, because of NR’s unique optical properties, which change with dissolved ...

CO2 Sensor Calibration: What You Need to Know |

All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors.

TECHNICAL NOTE : Dissolved CO2 and Units of Measurement

CO2-Pro Atmosphere Sensor measures both air and surface water pCO2 for carbon flux measurements. Dissolved CO 2 and Units of Measurement TECHNICAL NOTE : Introduction Dissolved carbon dioxide sensors often utilize equilibrator systems with semi-permeable membranes in order to measure CO2 directly in the gas phase, most commonly using an infrared detector. As a result, these …
