Picarro G2103 – Gas Concentration Analyzer

For precise measurement of ammonia

The Picarro G2103 laser spectrometer is the only instrument that can measure ammonia in environments as diverse as agricultural test barns and semiconductor manufacturing. It is portable, rugged and has sensitivity in the ppb range. The analyzer has a huge dynamic measurement range and provides a linear response well into the ppm range. No dilution, concentration or other sample preparation is required. Therefore, the G2103 can be equally operated in remote, unattended air monitoring stations as well as in the laboratory as reference instrument.

Simultaneous, precise measurement of NH3 and H2O

  • Sensitivity, precision and accuracy in the billionths range with no drift
  • Fast, continuous, real-time measurements with no interference
  • Wide dynamic range with high linearity
  • Field and laboratory use without consumables
  • Installed and ready to use in minutes
  • Robust and insensitive to changes in ambient temperature
