This air sampler is conveniently sized and portable. It fills two 2.5 L glass flasks, in series, sampling the air taken from the top of a telescoping 5.4 m mast. Used in NOAA Carbon Cycle Greenhouse Gas (CCGG) cooperative air sampling network for ground-based flask pair sampling.
Used by NOAA to collect samples for analysis of CO2, CH4, N2O, CO, H2, and 50 other gas and isotope species.
