“…More than 600 peaks were obtained on gas chromatograms, and approximately 300 compounds have so far been either identified or tentatively identified in the neutral, acidic, and basic fractions of solvent extracts, including aliphatic and aromatic hydrocarbons, phthalates, benzaldehydes, phenols, aliphatic and aromatic ketones, mono-and dicarboxylic acids, amines, azaarenes, etc. The most abundant components were an unresolved mixture of hydrocarbons (ranging from 25 to 56 µg/L) and a homologous series of aliphatic monocarboxylic acids, which show a strong even-carbon-numbered predominance in the Cio-C30 range (7)(8)(9)(10)(11)(12)(13)(14)(15)(16) gg/L), with a maximum at C16. Smaller amounts of normal hydrocarbons (0.6-2 µg/L), nitrogen-and oxygen-containing polycyclic aromatics sucb as fluoren-9-one, phenanthrene-9,10-dione, and isoquinoline, and polycyclic aromatic hydrocarbons (0.05-0.1 µg/L) were also identified.…”

“…Detection limits of this method that used a capillary column is lower than 1 ng described in the paper by Hoshika and Muto (1978) that used a packed column for analysis of indoles in Tenax-GC tube, so this method is found to be more sensitive than better than the their method. On the other hand, the method using HPLC (High Performance Liquid Chromatography) published by Willig (2004) presented 0.01 ng of detection limits of indole and skatole.…”

The purpose of this study is to compare the sampling methods for monitoring indoles (phenol, p-cresol, indole and skatole) in airs of swine facility. As the collecting methods of indoles in air, Tenax-TA adsorption tube and solid phase microextraction (SPME) were examined. For the preparation of calibration curves of indoles concentrated in Tenax-TA, the standard indoles solutions were spiked in each of Tenax-TA tubes and thermally desorbed (ATD) into a gas chromatograph combined with mass detector (GC/MS). And for the preparation of calibration curves by SPME, indoles in the standard gaseous solution prepared by evaporating the aqueous solution that contained indoles into a polyester sampling bag were extracted with SPME fiber and subsequently analyzed by the GC/MS. Two sampling methods were evaluated for extracting indoles present in swine building environments. Results indicated that the SPME method using Polydimethylsiloxane/ Divinylbenzene (PDMS/DVB) fiber was more effective than Tenax-TA method in extracting indoles. The gas chromatographic analysis showed that the linearities of calibration curves and detection limits were useful for detection of indoles in swine airs. The field tests also showed that considerably different levels of indoles were present in various parts of the swine building.
