Cavity Ring-Down Spectroscopy Analyzer for Carbon Dioxide Methane and Water - Flight Ready

CRDS Analyzer for flight ready CO₂/CH₄/H₂O - G2301-m

Makes taking measurements in the most difficult environment simple as pie while maintaining unmatched precision levels

From the Amazon Rainforest to the skies over California's Central Valley, Picarro's flight analyzers raise the bar for high-altitude greenhouse gas measurement technology. Scientists can expect the high sensitivity, precision and accuracy available from all Picarro’s greenhouse gas analyzers with the added ability to automatically adapt to the rapidly changing pressures and temperatures experienced during flight. In addition, the Picarro 2301-m flight analyzer features a 1 Hz measurement speed to provide the increased data resolution needed for flight-based research.

Complete understanding of global warming, modeling, protocols and international agreements, as well as local, national and global verification, can all require the need to measure the three principal greenhouse gases (CO₂, CH₄ and H₂O). The Picarro G2301-m complements other Picarro instrumentsinstalled on tall towers and other land-based monitoring sites. It enables vertical profile and upper atmosphere measurements to be recordedduring aircraft flight. The resulting data yields important information on boundary layer conditions and atmospheric mixing, which are both essentialcomponents in quantifying atmospheric concentrations of greenhouse gases. When not flying, the G2301-m operates equally well in the lab, on a boat, in a tower, or in any remote continuous monitoring station.
Because the G2301-m analyzer is based on CRDS technology, there is no crosstalk between the CO₂, CH₄ and H₂O and all three species areunaffected by changes in other gases. No dilution, concentration or other sample prep is required. As regulations and protocols are established forgreenhouse gases, the ability of the same instrument to perform lab and field measurements can be a key benefit.

Picarro's CRDS analyzers allow data to be accessed in real time through serial, USB and Ethernet protocols, and can be equipped with an analogoutput option as well. The data is continuously archived in ASCII-formatted files on an internal hard drive - this is ideal in situations where the analyzer may be located remotely during long measurement campaigns and in which data retrieval or remote connectivity may be infrequent. The analyzers are also designed automatically restart themselves and resume data collection if there is a temporary loss of power.
