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
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 40-0008 Rev. D G5131-i User Manual...
Page 9
Picarro instruments gather measurements from an “empty” cavity by switching the light to wavelengths that are not absorbed by the target molecules.
Page 10
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. G5131-i User Manual P/N 40-0008 Rev. D...

The coordinator gets data from the GUI and creates a single file, the data is reported as a function of sample. 5. Before shutdown, Picarro recommends flowing clean dry air (CDA) through the analyzer for several minutes. This prevents moist gas in the cavity from condensing on the optics as the analyzer cools.
