Gas Chromatography (FID)

The measurement programme of the CH4 has been run by CESI RICERCA since February 1991 (at beginning by means of biweekly samplings until December 2002 and then by means of continuous measurements since January 2002). The measurements have been stopped from May 2006 to October 2007. Since 2008 the minimum temporal resolution for the mean values is based on hourly averages.

Instrument: GC-FID, NIRA Venus 301

Duration of the analyses' cycle: 120 s.

Detection limit: 20 ppb.

The calibration measurements are realized by means of two working gas standard referred to primary standard.

The working standard are systematically measured every six hours.

CMDL X83 up to 2007. Since 2008 NOAA04 Scale. Convertion factor is: 1.0124. So, CMDL X83 * 1.0124 = NOAA04.

In 2009, all CMDL X83 scale data have been expressed in NOAA04 scale.

FLAG: "1" means "valid data". The data is considered correct but no criteria, at the moment, has been applied to identify the background data; "2" means "invalid data" (for example, instrumental problems due to the missed electrical power, incorrect calibration measurements, sampling flow incorrect and so on)
