  • Different Technologies used by DPCC

    DPCC have Six CAAQMS.

    4 working on Conventional Technology.

    2 on DOAS based Open Path Technology for gaseoussampling.

    For Particulate all the stations are working on-attenuation based principle.

    All the technology approved by USEPA.

  • Differential Optical Absorption Spectroscopy(DOAS)

    Uses the unique absorption of specific electromagneticenergy wave lengths by chemicals in the ultra Violet(UV),Visible (V) and near infrared (NIR) spectrum to identify andquantify individual chemicals .

    The system includes a light emitter that collimates the lightfrom a source lamp, a transmitting telescope a telescope thatcollects the attenuated light beam , a spectrometer , a singleor multichannel receiving/detector unit and a control andprocessing computer.

    Light Path used at Civil Lines is 120 m and at IGI airport 180m.

  • Conventional technology

    Separate analyzer for each gas is installed and air sucked through manifold to a analyzers and analysed for specific gas/ parameters.

  • Present Status: Trend Analysis
