“…The GC was connected to a custom built cryosampling thermal desorption system (GER-STEL GmbH & Co. KG, Mülheim an der Ruhr, Germany) for the preconcentration of VOCs. The setup and its use for filter analysis are described in detail by Iannone et al (2007) and Fisseha et al (2009), respectively. Note that the temperature of the thermal desorption system was set to 225 • C, according to the desorption temperature of the ACM collector.…”

Abstract. In many environments organic matter significantly contributes to the composition of atmospheric aerosol particles influencing its properties. Detailed chemical characterization of ambient aerosols is critical in order to understand the formation process, composition, and properties of aerosols and facilitates source identification and relative contributions from different types of sources to ambient aerosols in the atmosphere. However, current analytical methods are far from full speciation of organic aerosols and often require sampling times of up to one week. Offline methods are also subjected to artifacts during aerosol collection and storage.In the present work a new technique for quasi on-line compound specific measurements of organic aerosol particles was developed. The Aerosol Collection Module (ACM) focuses particles into a beam which is directed to a cooled sampling surface. The sampling takes place in a high vacuum environment where the gas phase from the sample volume is removed. After collection is completed volatile and semi-volatile compounds are evaporated from the collection surface through heating and transferred to a detector.For laboratory characterization the ACM was interfaced with a Gas Chromatograph Mass Spectrometer, Flame Ionization Detector system (GC/MS-FID), abbreviated as ACM GC-MS. The particle collection efficiency, gas phase transfer efficiency, and linearity of the ACM GC-MS were determined using laboratory generated octadecane aerosols. The ACM GC-MS is linear over the investigated mass range of Correspondence to: A. Kiendler-Scharr (a.kiendler-scharr@fz-juelich.de) 10 to 100 ng and a recovery rate of 100% was found for octadecane particles.The ACM GC-MS was applied to investigate secondary organic aerosol (SOA) formed from β-pinene oxidation.Nopinone, myrtanal, myrtenol, 1-hydroxynopinone, 3-oxonopinone, 3,7-dihydroxynopinone, and bicyclo[3,1,1]hept-3-ene-2-one were found as products in the SOA. The ACM GC-MS results are compared to quartz filter samples taken in parallel to the ACM GC-MS measurements. First measurements of ambient atmospheric aerosols are presented.

While VOC analysis by GC-IRMS is well established, collecting ambient VOC for the isotope analysis is challenging.…”

“…Cryogenic sampling has been used to collect VOCs from very large volumes of air (Bill et al, 2004Iannone et al, 2007Zuiderweg et al, 2011), but the technical and logistical challenges for field sampling are substantial. Selective sampling on adsorbent cartridges is a widely used inexpensive method for measurement of VOC concentrations and has recently been applied to collect VOC samples for isotope ratio analysis (Eckstaedt et al, 2011(Eckstaedt et al, , 2012.…”

“…This volume typically ranges from several liters for whole air sampling to several hundred liters or more for cryogenic sampling (Gensch et al, 2014, and references therein). With sample volumes of up to 80 L, the method developed in this work allows collection of significantly larger samples than methods using whole air sampling but not of the extremely large sample volumes that can be used by some cryogenic methods (Bahlmann et al, 2011;Bill et al, 2004;Iannone et al, 2007). However, the adsorptive sampling method described in this paper requires less expensive instrumentation than cryogenic sampling and can be conducted in the field with instrumentation that is similar in requirements (electrical power, weight, storage, shipment) to whole air sampling in pressurized containers.…”

Abstract.A technique for compound-specific analysis of stable carbon isotope ratios and concentration of ambient volatile organic compounds (VOCs) is presented. It is based on selective VOC sampling onto adsorbent-filled cartridges by passing large volumes of air (up to 80 L) through the cartridge. The hydrocarbons are recovered by thermal desorption followed by two-step cryogenic trapping and then are separated by gas chromatography in the laboratory. Once separated, individual VOCs are subjected to online oxidation in a combustion interface and isotope ratio analysis by isotope ratio mass spectrometry. The method allows measurements of stable carbon isotope ratios of ambient aromatic VOCs present in low pptV to ppbV levels with an accuracy of typically better than 0.5 ‰. The precision of concentration measurements is better than 10 %. Examples of measurements conducted as part of a joint Environment Canada-York University (EC-YU) measurement campaign at a semi-rural location demonstrate that the ability to make accurate measurements in air with low VOC mixing ratios is important to avoid bias from an overrepresentation of samples that are strongly impacted by recent emissions.

Abstract. Stable isotope analysis has become established as a useful method for tracing the budgets of atmospheric trace gases and even atmospheric oxygen. Several new developments are briefly discussed in a systematic way to give a practical guide to the scope of recent work. Emphasis is on applications and not on instrumental developments. Processes and reactions are less considered than applications to resolve trace gas budgets. Several new developments are promising and applications hitherto not considered to be possible may allow new uses.
