    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

    A cavity containing gas that absorbs light will have a shorter ring- down time than an empty cavity. 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 40-0007 Rev. C G5102-i 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.

  • 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.
