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

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 carbon dioxide (dCO2) concentrations. In the present study, optical sensitivity of NR was quantified as a function of changes in absorption and emission spectra to dCO2 ...

Carbon Dioxide (CO HVAC Basics - Honeywell

Do not confuse carbon dioxide (CO2) with carbon monoxide (CO), a highly toxic gas that is also a byproduct of combustion in furnaces, fireplaces and automobiles. Carbon monoxide (CO) can be harmful, even at very low levels (25 to 50 ppm). CO2 as an IAQ Indicator Claims that CO2 sensors are indoor air quality (IAQ) sensors are inaccurate. CO2 levels are one piece of the undefined indoor air ...

Carbon dioxide sensor - Wikipedia

NDIR sensors are most often used for measuring carbon dioxide. The best of these have sensitivities of 20–50 PPM. Typical NDIR sensors cost in the (US) $100 to $1000 range. NDIR CO 2 sensors are also used for dissolved CO 2 for applications such as beverage carbonation, pharmaceutical fermentation and CO 2 sequestration applications.

How does an NDIR CO2 Sensor Work? |

Like every IR gas sensor, the analyzer at Mauna Loa used the same basic principle for measuring CO2. It has an infrared light radiation source at one end of a gas sample tube and an IR detector at the other. The band of infrared radiation is very close to the absorption band of CO2. As a result, the amount of light radiation that is absorbed by the CO2 molecules is proportional to the amount ...
