Carbon Dioxide (CO2) in Blood: MedlinePlus Medical Test

What is a carbon dioxide (CO2) blood test? Carbon dioxide (CO2) is an odorless, colorless gas. It is a waste product made by your body. Your blood carries carbon dioxide to your lungs. You breathe out carbon dioxide and breathe in oxygen all day, every day, without thinking about it. A CO2 blood test measures the amount of carbon dioxide in your blood. Too much or too little carbon dioxide in the …

Principle of NDIR CO - SENSOR+TEST

Principle of NDIR CO2 sensors The NDIR(Non-Dispersive Infrared) utilizes the phenomenon that a gas The amount of absorbed IR light is proportional to the concentration. For example, H2O has the maximum absorbance at and ㎛, SO2 at ㎛, CO2 at ㎛, NO at ㎛. An IR source at the end of the measurement chamber emits light into

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the …

7 Reasons Why You Should Measure CO2 Inside Buildings ...

· CO2 can be hazardous in one of two ways: by displacing oxygen in the blood or acting as a toxin. ... Figure 3 is a diagram of a simplified NDIR based CO2 sensor. At one end is a LED source emitting infra-red light and at the other end is a detector with a specific light filter to detect only CO2. Gas diffuses into a chamber between the LED source and detector. The amount of CO2 in the chamber ...
