History

Work topics

• Determination of gas and particulate atmospheric pollutants by optical methods.

The most relevants woks

• Measurement of SO₂, NO₂ in industrial emissions by using non-dispersive optical techniques.
• Measurement of stratospheric ozone by using non-dispersive differential absorption
• Measurement of SO₂, NO₂ and ozone in urban environment by using open column differential optical absorption spectrometry (DOAS).
• Measurement of NO₂ in tropospheric column by using multiaxial DOAS.

Available equipment

• An industrial chimney-stack with heating and central measure of calibrated gases EPA.
• An infrared Interferometer with Fourier transform ( 0.125 cm^-1maximum resolution).
• A Spectrograph (25 cm focal distance)
• A multichannel spectrograph.
• A Non-dispersive gases-meter.
• A differential optical absorption equipment (DOAS) for the determination of SO₂, NO₂ and ozone in urban environments.
