Analytical Issues Artifact in ethyne: coelution of unidentified CFC/HCFC – Current version subtracts constant amount (22 pptv) ATTREX (2013) + ATTREX (2011)

Analytical Issues (2) Moisture related artifact during sample injection – Sample response different from standard response – Use long-lived tracer to normalize responses CFC114 (lifetime ~ 189 yr) Expected variation ~1%/100 – 150 ppb O3 – Results in some loss of samples when CFC114 analytical problem (H2O) – Effect depends on volatility (GC retention) less effect for more volatile than 114 – CFC12, CH3Cl, HFC134a – Introduces extra imprecision into long-lived tracers; less of an impact for short-lived substances

Example (RF05) : Methyl nitrate

Analytical Issues (3) Original working standard vented during shipment. – Last minute replacement needed calibration – Still some standard checks required with primary standards when SEAC4RS analysis complete.
