“…The analysis of portions of the volatile profile on a second GC phase with a different selectivity allows an orthogonal separation of complex volatile samples and the detection of volatiles that are not detected on conventional one-dimensional GC. Thus repetitive ‘heart-cutting’ multidimensional GC-MS of lavender essential oil [34] more than tripled the number of peaks detected with decreased peak widths and improved peak capacity. The combination of MD-GC analysis with gas chromatography olfactometry (GC-O) allows exhaustive characterization of odor active volatiles in complex essential oils and food plants and the resolution of key odorants from co-eluting metabolites [35].…”

Volatile organic compounds (volatiles) comprise a chemically diverse class of low molecular weight organic compounds having an appreciable vapor pressure under ambient conditions. Volatiles produced by plants attract pollinators and seed dispersers, and provide defense against pests and pathogens. For insects, volatiles may act as pheromones directing social behavior or as cues for finding hosts or prey. For humans, volatiles are important as flavorants and as possible disease biomarkers. The marine environment is also a major source of halogenated and sulfur-containing volatiles which participate in the global cycling of these elements. While volatile analysis commonly measures a rather restricted set of analytes, the diverse and extreme physical properties of volatiles provide unique analytical challenges. Volatiles constitute only a small proportion of the total number of metabolites produced by living organisms, however, because of their roles as signaling molecules (semiochemicals) both within and between organisms, accurately measuring and determining the roles of these compounds is crucial to an integrated understanding of living systems. This review summarizes recent developments in volatile research from a metabolomics perspective with a focus on the role of recent technical innovation in developing new areas of volatile research and expanding the range of ecological interactions which may be mediated by volatile organic metabolites.

“…MDGC is necessarily at argeteda pproach, applied to certainr egion(s) of the 1 Dc olumne lution, [21] although novel approaches allow advanced operation, which makes se-quentialm ulti heart-cut operation possible. [22] In contrast to chiral analysis with an e 2 Dc olumn in MDGC,f or GC GC the obvious approach is to use an enantioselective 1 Dc olumn, termed eGC GC. Given that the 2 Dc olumn in GC GC is short, it is usually not suitable for achieving chiral separation, which normally requires al ong column to accomplish sufficient enantiomericr esolution.…”

“…This overcomes potential problems of peak overlap if a single enantioselective column is used. MDGC is necessarily a targeted approach, applied to certain region(s) of the 1 D column elution, although novel approaches allow advanced operation, which makes sequential multi heart‐cut operation possible . In contrast to chiral analysis with an e 2 D column in MDGC, for GC×GC the obvious approach is to use an enantioselective 1 D column, termed e GC×GC.…”

Addressing the Challenges to Identification in Gas Chromatography by Increased Resolution and Enhanced Detection Modalities

In the past 15+ years, gas chromatography (GC) has undergone a renaissance in its implementation on the basis of the "disruptive" technology of comprehensive two-dimensional gas chromatography (GC×GC). With a foundation based upon a two-column GC separation approach, GC×GC significantly alters the classical multidimensional gas chromatography (MDGC) method by employing very fast separation on a second dimension ( D) after a conventional one-dimensional (i.e., single column; 1D) column separation. This allows the experimentalist to apply the advantages of multidimensionality to the total sample rather than to just discrete zones of the 1D separation that characterizes MDGC. This requires a new "language" to describe GC×GC separations, applied to the first dimension ( D) and D, and consideration of the modulation processes that define the transfer of analyte from the D to the D. The present review is based on the FACS Foundation lectureship of the author given at the 17th Asian Chemical Congress of the Federation of Asian Chemical Societies (FACS). The award lecture and this manuscript is based on material deriving largely from research in the area of MDGC and GC×GC separations of the author.

“…Their successful implementation of a number of hybrid GC approaches in a single instrument [8,9,10,11,12] represents qualitative and quantitative developments to provide a convenient solution to overcome uncertainty of data correlation across multiple hyphenated systems. The use of cryogenic trapping and modulators, with flow switching explored by the group [17,18,19,20], allows the focussing and/or concentration of the volatile analytes in various modes of operation, which improves separation peak capacity and enhances the quality of analyte characterisation.…”

Multidimensional approaches in gas chromatography have been established as potent tools to (almost) attain fully resolved analyses. Flavours and odours are important application fields for these techniques since they include complex matrices, and are of interest for both scientific study and to consumers. This article is a review of the main research studies in the above theme, discussing the achievements and challenges that demonstrate a maturing of analytical separation technology.
