pobieranie próbek powietrza do butli ze stali nierdzewnej

HATS has been analyzing air samples collected in flasks since 1977. Originally set up under the auspices of the Geophysical Monitoring for Climatic Change (GMCC) division of NOAA's Air Resources Laboratory (NOAA/ARL), this program...
Electropolished, stainless-steel flasks (300 ml, Whitey with Nupro SS-4H metal bellows valves) were collected weekly in pairs, filled to 1.5 atm with a metal bellows pump to minimize contamination of CFC's by plastics or other elastomers, and shipped to Boulder for analysis. All samples were analyzed for N2O, CFC-11, and CFC-12 on a Hewlett Packard 5710A, electron-capture gas chromatograph (GC/ECD) equipped with a Porasil A column. In 1986, when GMCC became the Climate Monitoring and Diagnostics Laboratory and HATS was formed, efforts were initiated to increase the number of gases measured from each flask.
Larger flasks (850 ml, Biospherics) were obtained and KNF Neuberger diaphragm pumps (Model UN05SV1) were sent to the sampling sites so that the flasks could be pressurized to 4 atm absolute pressure.
