Better solutions for air quality awareness

PIGC with sunglasses
Technology & Features
  • Patented Pupil Imaging Gas Correlation – PIGC™ technology
    •  Based on NASA satellite measurement heritage (HALOE), bringing performance and reliability to the ground instrument design
  • Remote sensing technology, integrating whole atmospheric column
  • Can detect a series of key GHG gases and some others simple molecules, as well as toxic gases at low ppm concentrations
    •  The primary interests include methane (CH4) and carbon dioxide (CO2)
  • Continuous 24/7 (1-D) or quasi continuous measurements (3-D) for daily operation under sunny to moderately cloudy skies with high temporal resolution
  • Simple optical layout; Easy to build (COTS components)
    •  Small system (≈15x15x30 cm)

 

Advantages
  • Wide detection coverage: Measures emissions either a single well head, an entire gas production field, and industry plant, and entire city, a country, or even a continent
  • Matches or exceeds the precision and accuracy of spectrometers 10 to 100 x more expensive
  • “Drop & Forget” autonomous grids; no disruption to customer operations
  • Can be operated from fixed or mobile platforms
    •  Vehicle mounted sensors can produce effective grids of data by moving around and through targeted areas (e.g. useful for pipeline monitoring)
  • Sensor grids monitor a full atmosphere volume (3-D) above an observed area
    •  Instead of at a limited number of fixed points (0-D) or on a restrictive linear closed path (1-D)
  • Precise identification: Accurately detect, analyze, and identify (pinpoint) the source of fugitive emissions
  • High accuracy and excellent sensitivity
    •  Target gas specificity with PIGC™ optical gas correlation technique
  • Wireless communication (cell phone or satellite networks)
  • Low data rate & bandwidth required (few bytes per measurement)
  • Internet secure web-based reporting to end-customers
  • Simplified diagnostic: remote verification and local Bluetooth connectivity
  • Auto calibration for long-term stability allowed by auto-calibration
  • Low power; operating on solar cells and batteries
  • Smaller and cheaper than any competing solution
  • Robust, rugged, reliable, and simple to operate
 
Benefits
  • Improves site efficiency, reduces production losses, and allows lowering emissions
  • Valuable tool for public and environmental health & safety impact assessments
  • Valuable tool for airfield mapping at ground level and in overhead volume
  • Easy network deployment: Low installation costs, just Drop & Forget
  • Remote connection and autonomous operation
  • Significant capital expenditure reduction (Capex Savings)
  • Requires less devices and field wiring compared to a multi-point detector solution.
  • Wide area coverage reduces the need and installation costs of fixed point devices.
  • Significant operating expenditure reduction (Opex Savings)
    •  No consumable sensing elements or any need for routine test gases
    •  No human interaction are needed
