“…A number of different sorbents may be used for trapping VOCs and include carbon (30) and a synthetic medium like Tenax™-GC (2,6-diphenylp-phenylene oxide polymer) (2,8,33,57,70,71,88,96,99). In general, Tenax™-GC is the preferred medium, as it has the advantages over most other common sorbents of being thermally stable (127)(128)(129) and chemically inert (127). However, aromatic contaminants such as toluene that may originate from the degradation of Tenax™-GC during its manufacture and storage can ultimately result in chromatographic peaks that are artifacts.…”

The formation of volatile organic compounds (VOCs) in polyethylene (PE) is a topic of concern to industries involved in the packaging of items such as foodstuffs and pharmaceuticals that are sensitive to organoleptic contamination. This article reviews the available literature on VOCs that originate from PE during its manufacture, processing, storage, and service life. The package-product interactions that may occur between PE and packaged foodstuffs are also considered together with the wide range of methods for the analysis of VOCs. The following analytical methods are discussed: (i) sensory evaluation, (ii) chromatographic techniques and their associated sampling techniques, including ORDER REPRINTS the "hot-jar" method and dynamic headspace sampling, (iii) gas chromatography-olfactory sensing, and (iv) artificial olfaction or "electronic nose" technology.

“…Tenax TA is frequently used in environmental and trace analysis as an adsorbent for enriching traces in the ppm to ppt range [1,2]. Compared to extraction with ultra-pure solvents the thermal desorption of Tenax offers the benefit of working with the undiluted sample and, compared to cold traps, that of relatively low retention of water [3]. Also, its high thermal stability (up to approx.…”

SummaryThe chromatographic separation properties of long, thin adsorption tubes enable substance-specific quantitative enrichment and reduction to be achieved when sampling and thermal desorption are carried out in the same flow direction.The specific retention volumes, and also the breakthrough and peak end volumes, of 69 compounds in the boiling range between -1 64 and 126OCand of a relative molecular mass between 16 and 11 9 were determined at temperatures between 30 and

“…However, because of the hydrophilic characteristic of methanol with a carbon number of only one, it is not easily adsorbed by Tenax, whereas the situation was the reverse for BTX. Some studies on Tenax [25][26][27][28] have primarily explained the reasons why BTX was still retained in the absorbent while most of the solvents were removed by nitrogen flow at room temperature. Our present study on a novel SPE technique has exhibited good agreement with the previous works.…”

Comparison of SPE-TD-GC-FID with UPLC-PDA and GC-MS Methods for Analysis of Benzene, Toluene and Xylene Isomers in Solid-Liquid Mixing Paints

Three methods were developed for analysis of benzene, toluene, p-xylene, m-xylene and o-xylene (BTX) in a solid-liquid mixing paint. These methods were based on solid phase extraction-thermal desorption-gas chromatography with a flame ionization detector (SPE-TD-GC-FID), ultra performance liquid chromatography-photodiode array detector (UPLC-PDA) and gas chromatography-mass spectrometry (GC-MS). At their optimum conditions of operation, the developed methods were compared in terms of recovery, sensitivity, selectivity and universality. Although the time required for GC-MS analysis was shorter than for GC-FID and UPLC-PDA, it offered relatively poorer recoveries and suffered from matrix interferences. All of the mentioned methods were proven to be ideal for the analysis of targeted analytes; SPE-TD-GC-FID was particularly fit for the determination of trace level BTX residues present in the complex matrix. As one of the sample pretreatment techniques, the novel SPE also showed some selectivity towards BTX and was found to be superior to the conventional SPE.
