The heart of the Picarro is a sophisticated time-based measurement that uses a laser to quantify spectral features of gas phase molecules in an optical cavity. Picarro unique design enables an effective measurement path length of up to 20 kilometers in a compact cavity, which results in exceptional precision and sensitivity in a small footprint. Picarro uses a patented, high-precision wavelength monitor to maintain absolute spectral position, which combats the drift inherent in all lasers and ensures accurate peak quantification\"","keywords":"BAS, methane, carbon dioxide","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/9683/?format=json"],"instrumentType":"gas_chromatograph","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/111859/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/111860/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/168426/?format=json"]}
