Statement

CH4:

Methane is measured by using a customized GC-FID (Agilent 6890N ). Separation is performed on a double column system (precolumn/backflush: Unibeads 1s; analytical column: Molecular SIeve 5A), isothemrically. Length of run is 15 min long. Each ambient air sample is bracketed with calibration runs. The working standard are based on NOAA2004 scale.

SF6:

Sulfur Hexafluoride is measured by using a GC-ECD (Agilent 6890N); separation is performed on a double column system (precolumn/backflush and analytical column, both Hayesep Q), isothemrically. Each run is 15 minute long. Each ambient air sample is bracketed with calibration runs. The working standards are based on NOAA2006 scale

CO:

Carbon monoxide (CO) is measured by using a customized GC-FID (Agilent 6890N ), after reduction to methane thorough a Hot Nikel-Catalizer; separation is performed on a double column system (precolumn/backflush: Unibeads 1s; analytical column: Molecular SIeve 5A), isothemrically. Length of run is 15 minutes. Each ambient air sample is bracketed with calibration runs. The standard are based on NOAA2004 scale.

N2O:

Nitrous oxide is measured by using a customized GC-ECD (Agilent 6890N); separation is performed on a double column system (precolumn/backflush and analytical column, both Hayesep Q), isothermically. Length of run is 15 min long. Each ambient air sample is bracketed with calibration runs. The standard are based on NOAA2006 scale.
