“…For the interested reader, there have been a number of reviews since the 1970s on CC detectability/analysis [19,68,69], and VOCs in general [3,70]. Barro et al [62] reviewed CC-detection methods and their limit of detection (LOD); however, the LODs are listed with a diverse set of units (e.g., pg, ng m −3 or μmol L −1 ), which makes direct comparison between different methods difficult, as the sample sizes have not been specified.…”

“…In this type of complex mixture analyses a GC-MS procedure was found better for the separation of large number of carbonyl compounds (Dong & Moldoveanu, 2004). Otson and Fellin (1988) described various methods applicable for the measurement of specific aldehydes.…”

The atmosphere is a particularly difficult analytical system because of the very low levels of substances to be analysed, sharp variations in pollutant levels with time and location, differences in wind, temperature and humidity. This makes the selection of an efficient sampling technique for air analysis a key step to reliable results. Generally, methods for volatile organic compounds sampling include collection of the whole air or preconcentration of samples on adsorbents. All the methods vary from each other according to the sampling technique, type of sorbent, method of extraction and identification technique. In this review paper we discuss various important aspects for sampling of volatile organic compounds by the widely used and advanced sampling methods. Characteristics of various adsorbents used for VOCs sampling are also described. Furthermore, this paper makes an effort to comprehensively review the concentration levels of volatile organic compounds along with the methodology used for analysis, in major cities of the world.

“…However, the sampling time needed for the DPE method with the analysis of spectrophotometer was relatively long due to the limited sensitivities. Generally speaking, derivatization techniques with chromatographic approaches can enhance sensitivity as well as selectivity [20]. Since the determinations of aldehydes with great sensitivities can be achieved by the derivatization with O-2, 3,4,5,6-(pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA) followed by the analysis with gas chromatography [21][22][23], lower detection limits for the measurements of ambient ozone might be reached if pyridin-4-aldehyde formed from the reaction between ozone and DPE was further derivatized with PFBHA to form oximes and then analyzed by gas chromatograph (GC).…”
