Abstract: Odorous gases associated with livestock operations are complex mixtures of hundreds if not thousands of compounds. Research is needed to know how best to sample and analyze these compounds. The main objective of this research was to compare recoveries of a standard gas mixture of 11 odorous compounds from the Carboxen/PDMS 75-m solid-phase microextraction fibers, polyvinyl fluoride (PVF; Tedlar), fluorinated ethylene propylene copolymer (FEP; Teflon), foil, and polyethylene terephthalate (PET; Melinex) air sam… Show more

“…Metallized FEP bags had a significantly cleaner background than that of Tedlar bags, which were contaminated with considerable amounts of DMAC and phenol as well as other interferences containing Si m/z signature ions originating from silicon septum material. Significant amounts of DMAC and phenol in Tedlar bags were previously reported by Koziel et al (2005), Trabue et al (2006), and Mochalski et al (2013).…”

“…However, most of these odor-causing VOCs are polar, reactive, and highly sorptive onto surfaces of sampling media, which increases the challenge for their measurement. The use of industry-standard Tedlar bags for odor sample collection from CAFOs has been challenged by the evidence of odorous VOC losses and background interferences (Keener et al, 2002a;Koziel et al, 2005;Trabue et al, 2006). It is also known that CAFO odor measurements are often associated with high uncertainties.…”

“…However, slow filling of canisters and sampling in humid environments can result in condensation of water at the sample container inlet and inside canisters both of which can lead to potential loss of compounds (McClenny et al, 1999;Wang and Austin, 2006). It has also been shown that certain polar compounds associated with AFOs do not lend themselves to canister analysis (Koziel et al, 2005). In fact, volatile fatty acids (VFAs) have not been detected with canister sampling and analysis from animal feeding operations (Koziel et al, 2005;Blunden et al, 2005;Filipy et al, 2006) and they are known to be a significant VOC associated with animal production (Zahn et al, 1997;Zahn et al, 2001;Ngwabie et al, 2008).…”

Even alternative air sampling techniques such as sorbent tubes (USEPA Method TO-17) have their own short comings especially when sampling in humid environments using molecular sieve sorbents (Helmig and Vierling, 1995;Gawlowski et al, 1999;Trabue et al, 2008a).…”

“…The use of canisters in quantifying odorants has been shown to be of limited value due to low recoveries of polar compounds (14). The use of SPME fibers is limited due to complexity of calibrating fibers to match environmental conditions, reverse diffusion of compounds, and competitive sorption (15)(16)(17).…”
