The Picarro G2401 gas concentration analyzer provides simultaneous, precise measurement of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification.
Picarro G2401
Description
The Picarro G2401 greenhouse gas concentration analyzer enables simultaneous measurements of CO2, CH4, CO with part-per-billion (ppb) sensitivity and negligible drift over months of operation. The G2401 also features Picarro’s unique algorithms to correct for the dilution effect of H2O vapor and to report dry gas mole fractions of CO2, CH4 and CO. The G2401 is compliant with performance requirements established by The World Meteorological Organization (WMO), and other international networks, such as the Integrated Carbon Observation System (ICOS) for atmospheric monitoring stations.
The unique combination of continuous 4-species measurement, high precision, field deployability, and long-term reliability makes the G2401 the instrument of choice for greenhouse gas measurements. Patented Picarro cavity ring-down spectroscopy (CRDS) technology 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 analyzer. A meticulously designed small optical cavity incorporates precise temperature and pressure control.
As a result, the analyzer delivers a best-in-class combination of precision, accuracy, low drift, and ease-of-use.
