Halogenated gases

Halogenated gases measurements are performed by a Gas Chromotograph -MS (Agilent 6890/5973) preconcentration/ thermal-desorption(Unity-Markes).

Measurement of greenhouses gas concentration (CFC, HFC, HCFC,...). Air samples at the NCO-P are collected by drawing ambient air into 1-liter stainless steel flasks by means of an ultra clean air pump, over a period of about 10 min, reaching the pressure 1.8×105 Pa.

Air aliquots are then analysed by gas chromatography-mass spectrometry (Agilent 6890–5973 GC-MS) equipped with an auto-sampling/pre-concentration

unit (Markes International UNITY-Air Server).

Statement

GCMS is a powerful tool for identifying and quantifying volatile and semivolatile compounds in a variety of samples.

The gas chromatograph functions to separate a mixture into its constituents and the mass spectrometer performs the analysis which provides the fingerprint.

This fingerprint can be searched in a library of fingerprints to make an identification of unknowns.

For calibration purposes, every sample run is bracketed between two working standard runs.

Working standards are actual air samples in turn calibrated against the SIO2005 (Scripps Institution of Oceanography) – UB98 (University of Bristol) scales, used within the AGAGE network.
