“…Pre-concentration of the tracers resulted in the simultaneous pre-concentration of the interfering compounds. Before the use of EC-NICI, the compounds were removed by using catalytic scrubbers, and by using high-resolution capillary columns so that the compounds did not coelute with the PFCs (D'Ottavio et al, 1986;Lagomarsino, 1996). In EC-NICI-MS, however, there is no need for any additional removal of interfering compounds.…”

“…The next major development in the analysis of PFC tracer compounds was the development of a technique that could resolve all six of the isomers of PDCH, instead of just the four that could previously be resolved. This was accomplished by the use of a new fused-silica capillary column (Lagomarsino, 1996). The improvement in chromatography was later combined with the use of EC-NICI-MS (Simmonds et al, 2002).…”

The study of atmospheric dispersion has become increasingly important over the last 120 years or so. Research in exposure pathways, fate of pollutants, dispersion model evaluation and validation are all reliant on experimental data. The most common atmospheric tracer compounds in use at the present time are the cyclic perfluoroalkanes and sulphur hexafluoride. These compounds are non-toxic, nonreactive and have low atmospheric background concentrations although they are recognized as greenhouse gases. This review discusses their use relative to other tracer species. A brief history of their individual analyses is included. The review then seeks to give a concise description of some representative atmospheric tracer dispersion experiments in terms of range, duration and objectives, and tracers used. Concluding remarks relating to the future use of these species are also presented.

“…However, the analytical process can suffer interferences from other compounds such as halocarbons with more abundant concentration in the atmosphere as the ECD is non-specific. To overcome this problem, a catalytic reaction was introduced to remove halocarbons from the samples prior to quantification of PFCs [ 2 , 3 , 10 ].…”

The Application of TD/GC/NICI–MS with an Al2O3-PLOT-S Column for the Determination of Perfluoroalkylcycloalkanes in the Atmosphere

A modified method for the quantitative determination of atmospheric perfluoroalkylcycloalkanes (PFCs) using thermal desorption coupled with gas chromatography and detection by negative ion chemical ionization–mass spectrometry was developed. Using an optimized analytical system, a commercially available Al2O3 porous layer open tubular (PLOT) capillary column (30 m × 0.25 mm) deactivated with Na2SO4 was used for separation of PFCs. Improvements in the separation of PFCs, the corresponding identification and the limit of detection of PFCs using this method and column are presented. The method was successfully applied to determine the atmospheric background concentrations of a range of PFCs from a number of samples collected at a rural site in Germany. The results of this study suggest that the method outlined using the Al2O3-PLOT-S capillary column has good sensitivity and selectivity, and that it can be deployed in a routine laboratory process for the analysis of PFCs in the future research work. In addition, the ability of this column to separate the isomers of one of the lower boiling PFCs (perfluorodimethylcyclobutane) and its ability to resolve perfluoroethylcyclohexane offer the opportunity for single-column analysis for multiple PFCs.

“…PFCs can be detected down to background concentrations by enrichment on a solid adsorbent, separation by gas chromatography (GC), and detection using electron capture detection (ECD) (DeBortoli and Pecchio, 1985;Dietz, 1986;Lagomarsino, 1996;Straume et al, 1998). In recent years, due to the excellent selectivity and sensitivity and simple manipulation process, the analytical method with negative ion chemical ionization mass spectrometry (NICI-MS) for PFCs has increasingly been used (Begley et al, 1988;Galdiga and Greibrokk, 2000;Cooke et al, 2001;Simmonds et al, 2002).…”

An airborne perfluorocarbon tracer system and its first application for a Lagrangian experiment

Abstract.A perfluorocarbon tracer system (PERTRAS), specifically designed for Lagrangian aircraft experiments, has been developed by the Deutsches Zentrum für Luft-und Raumfahrt (German Aerospace Center, DLR). It consists of three main parts: a tracer release unit (RU), an adsorption tube sampler (ATS), and a tracer analytical system. The RU was designed for airborne tracer release experiments; meanwhile, it can be used on various platforms for different experimental purposes (here research vessel). PERTRAS was for the first time applied in the field campaign Stratospheric ozone: Halogen Impacts in a Varying Atmosphere (SHIVA) in November 2011. An amount of 8.8 kg perfluoromethylcyclopentane (PMCP) was released aboard the research vessel Sonne (RV Sonne) near the operational site of this campaign, Miri, Malaysia, on 21 November. The tracer samples collected using the ATS onboard the DLR research aircraft Falcon were analyzed in the laboratory using a thermal desorber-gas chromatography-mass spectrometry (TD-GC-MS) system. Guided by forecasts calculated with the Lagrangian model Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT), 64 tracer samples were collected onboard the Falcon approximately 5 and 25 h after the release, mostly with a time resolution of 1 min. Enhanced PMCP concentrations relative to ambient PMCP background values (mean: 6.62 fmol mol −1 ) were detected during three intersects of the fresh tracer plume (age 5 h), with a maximum value of 301.33 fmol mol −1 . This indicates that the fresh tracer plume was successfully intercepted at the forecast position. During the second flight, 25 h after the release, the center of tracer plume was not detected by the sampling system due to a faster advection of the plume than forecast. The newly developed PERTRAS system has been successfully deployed for the first time. The instrumental setup and comparisons between the measurements and HYSPLIT simulations are presented in this study.
