5 Greenhouse gases preparation Preparation by gravimetric method Sequential weighing and filling of components into cylinders Several dilution steps depending on the mole fraction Gas Mixture composition (µmol.mol -1 ) CH 4 CO 2 Ar O 2 N 2 Ref Ref Ref Ref Verification of 4 mixtures above with GC-FID (methanizer)
6 Gas samples from Cape Point Location (position and elevation) : 34 21' S, 18 29' E, elevation 230 meters above mean sea-level. The height of the ambient air intake is 260 m above sea level from the top of a 30 m high mast. Two freezing units (-4 and -45 C respectively) are used in series to dry the ambient air prior to analysis at the station and into pressurised gas cylinders Sampling into cylinders by oil free compressor filling up to 150 bar (RIX industries) Samples transported to Pretoria Sample conditioning for a week prior to analysis by CRDS NMISA CRDS calibrated with gravimetric mixtures prepared in the laboratory Linear response for CO 2 and CH 4 of the four mixtures prepared
