Understanding UV-DOAS Gas Sensors!

· Principles of UV-DOAS technology

Light Absorption

UV-DOAS gas sensors function by measuring how SO2 absorbs UV light. This absorption varies with SO2 concentration, aiding accurate detection. Each light wavelength corresponds to a specific gas absorption level. SO2 uniquely absorbs UV, making detection precise. Sensors identify gases by comparing light before and after passage.

Optical Depth

Optical depth relates to how far UV light penetrates the gas. Deeper penetration indicates lower gas concentrations. SO2’s presence alters the light’s path length. Sensor calibration is vital for interpreting optical depth accurately. A balance between depth and clarity ensures effective measurement.

Integration Time

Integration time is crucial for UV-DOAS sensors. It’s the duration for measuring light absorption. Shorter times yield rapid readings but may reduce accuracy. Longer times enhance detection sensitivity, important for low concentrations. Optimal integration time balances speed and precision.

Absorption Coefficient

The absorption coefficient quantifies how well SO2 absorbs UV. Higher coefficients indicate stronger absorption. It varies with gas composition and concentration. This coefficient is key to determining SO2 levels. Calibrating sensors for specific coefficients enhances accuracy.
