Multidimensional gas chromatography hyphenated to mass spectrometry and olfactometry for the volatile analysis of citrus hybrid peel extract

Determination of Volatile Flavour Profiles of Citrus spp. Fruits by SDE‐GC–MS and Enantiomeric Composition of Chiral Compounds by MDGC–MS

“…The heart‐cutting multidimensional gas chromatography–mass spectrometry (MDGC–MS) technique has been proved as an efficient and sensitive tool for chromatographic separation and was first demonstrated by Schomburg et al (). In this technique, the first non‐enantioselective column coated with an achiral polar stationary phase is used to pre‐separate the components of interest (first dimension), whereas in the second enantioselective column coated with a chiral stationary phase, fractions of chiral analytes are enantio‐separated after online transfer through a pneumatic or flow‐controlled dead‐volume heart‐cut interface (second column) (Tranchida et al ., ; Casilli et al ., ). A large number of studies on the volatile compounds of Citrus fruits have been carried out by using gas chromatography (GC), and GC‐mass spectrometry (MS) (Moshonas and Shaw, ; Tirado et al ., ; Njoroge et al ., ; Qiao et al ., ; Jiang et al ., ; Kelebek and Selli, ; Casilli et al ., ; Cannon et al ., ).…”

Rapid assessment of the authenticity of limequat fruit using the electronic nose and gas chromatography coupled with mass spectrometry

“…These substances are characteristic for citrus fruit, e.g., kumquat [13, 14]. These compounds were detected in peel extracts of limequat samples by Casilli et al [15]. Casilli et al also identified other terpenes in the studied samples: α-terpinene, α-phellandrene, α-terpinolene, or sabinene.…”

Evaluation of injection methods for fast, high peak capacity separations with low thermal mass gas chromatography

“…Other techniques for rapid column heating, such as thermal gradient chromatography [20][21][22][23] have shown promise as novel technologies in the fast GC field. The results we present herein, as well as the results presented in previous references have important implications for two-dimensional gas chromatography (GC × GC or GC-GC) [24][25][26]. Consideration of separation times, peak widths, flow rates, heating rates, and other instrumental parameters must be implemented in a way that adequately preserves the two-dimensionality of the data that make GC × GC and GC-GC such powerful techniques.…”
