    Spectroscopy (CRDS), on the other hand, is one thousand to one million more times sensitive. In Picarro analyzers, light from a single-frequency laser enters a cavity where three mirrors reflect the laser light as seen in Figure 1. The light...

  • 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. Picarro G2114 Analyzer User Manual...

  • Page 9: Converting Absorption Intensity To Concentration

    Determining absorption intensity at a specific wavelength requires comparing the ring-down time of an empty cavity to the ring-down time of a cavity that contains gas. Picarro instruments gather measurements from an “empty” cavity by switching the light to wavelengths that are not absorbed by the target molecules.
