PAH (Oil in Water) in Environmental Monitoring

PAH (Oil in Water) in Environmental Monitoring

Monitoring polycyclic aromatic hydrocarbons (PAHs) in water is essential for identifying oil contamination and protecting aquatic ecosystems. As key indicators of petroleum-derived pollution, PAH sensors enable rapid detection of hydrocarbon presence in surface water, groundwater, and industrial discharge environments.

AlpHa’s XC-PAH sensor utilizes patent-pending optical technology with the following unique features:

  • Industry-leading minimum detection limit at 0.2 ppb
  • Automatic temperature compensation
  • Analog (0 – 3 V) or digital (RS-485 MODBUS RTU) output formats
  • Options for custom OEM sonde multiparameter and stand-alone configurations

  • Minimum Detection Limit: < 0.2 ppb
  • Linearity: R2 > 0.99
  • PAH Range: 0 to 300 ppb (µg / L)
  • PAH Response Time:
    • Sonde: T100 ~2 seconds
    • Stand-alone: ~2 seconds
  • 温度范围:0 至 50°C
  • Max Pressure: 375 m 
  • Emission Wavelength: 420 – 590
  • LED Center Wavelength: 365 nm
  • Input Power:
    • Sonde: 5 – 36 VDC
    • Stand-alone: 6 – 36 VDC

There is a lot of exciting stuff going on in the stars above us that make astronomy so much fun. The truth is the universe is a constantly changing, moving, some would say “living” thing because you just never know what you are going to see on any given night of stargazing.

But of the many celestial phenomenons, there is probably none as exciting as that time you see your first asteroid on the move in the heavens.
