Adaptation of an olfactometric system in a GC-FID in combination with GCxGC/MS to evaluate odor-active compounds of wine

Foods and Contaminants Analysis Using Multidimensional Gas Chromatography: An Update of Recent Studies, Technology, and Applications

“…A study 41 was conducted to evaluate the performance of 8 commercial packages, including AnalyzerProXD (Spectral Works Ltd.), Canvas (J&X Technologies), Chroma-TOF (LECO), ChromSpace (SepSolv), ChromSquare (Shimadzu), GCImage (GCImage LLC), GasPedal (Decodon), 49 (B) Schematic diagram of low-cost olfactometry. 50 (C) SNAT 51 modulator and (E) dynamic pressure gradient modulation (DPGM) 52 configurations. P inlet and P aux are the pressure at the inlet of the 1 D column and the auxiliary gas pressure applied to the valve.…”

“…Food Chem. 2022, 370, 131004; 50 and OpenChrom (Lablicate). The assessment results were anonymized, as the aim was to establish a conceptual framework for benchmarking data analysis software (or the data analysis approach) as well as to highlight reliability.…”

“…Dashed lines represent alternative pathways for specific MDGC configurations, which may consist of multiple columns (C1, C2, ...), modulators (M1, M2), microfluidic switching devices such as Deans switches (DS1, DS2), cryotraps (CT1, CT2, CT3), detectors (D1, D2, ...), and preparative fraction collectors (P1, P2, ...) . (B) Schematic diagram of low-cost olfactometry . (C) SNAT modulator and (E) dynamic pressure gradient modulation (DPGM) configurations.…”

“…A low-cost olfactometry (O) design is shown in Figure E; 1DGC connects the sniff port made of a silanized T-shaped glass tube (deactivated with 98% TMCS), covered with aluminum foil, and coated with polyurethane for insulation to prevent condensation. GC effluent reaches the nose via a synthetic air flow controlled by a flow meter, humidified using temperature-controlled deionized water in a round-bottomed flask.…”
