  • Page 7: Introduction To Technology

    In the cavity, a series of mirrors reflects the infrared light through the sample, increasing the path length. For a Picarro cavity of only 25 cm in length, the effective path length of the cavity can be over 20 kilometers.

  • Page 8: Relating Ring-Down Time To Absorption Intensity

    As the light circulates in a cavity with a gas sample, the molecular absorption by the gas results in a decrease of the light intensity. P/N 40-0047 Rev D PI2114 User Manual...

  • Page 9: Converting Absorption Intensity To Concentration

    Picarro instruments gather measurements from an “empty” cavity by switching the light to wavelengths that are not absorbed by the target molecules. The analyzer subsequently measures ring-down times at wavelengths that are absorbed by the target gas.

  • Page 10: Spectral Precision And High Sensitivity Measurements

    Picarro analyzers calculate the baseline underneath a poorly resolved peak by modeling the absorption peaks from other surrounding molecules and subtracting contributions from neighboring peaks to the absorption intensity.
  • Page 11 For precise pressure control, the cavity pressure is monitored using a high- linearity pressure transducer. The system computer uses this pressure data in a feedback loop to control proportional valves that adjust the inlet and outlet gas flow of the cavity. PI2114 User Manual P/N 40-0047 Rev D...
