Quantitative analysis of automotive exhaust gas by Fourier Transform Infrared spectroscopy
For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO2, NO, NO2 and N2O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation ...

Hybrid Air Quality Monitoring Network – The future of urban monitoring
Rapid urbanization, industrialization, and a rise in vehicular pollution have severely affected air quality in cities. With growing concerns about air pollution and cascading effects across the population, air pollution is emerging as a significant problem. Vehicular pollution, road dust, construction, and industrial pollution are some of the major sources responsible for air pollution in Indian ...

How does Air Quality Sensor Calibration improve data accuracy?
Low-cost sensors have emerged as a sound solution to air quality monitoring with better spatial coverage. The prime concern over the large-scale deployment of these sensors is their accuracy. However, the cost-effectiveness and the ability of such systems to provide regulatory grade data has led to large-scale ground studies. Governments and research organizations play an elemental role in ...
