Optimization of enantiomer separation in flow-modulated comprehensive two-dimensional gas chromatography by response surface methodology coupled to artificial neural networks: Wine analysis case study

Recent Advances in Separation and Analysis of Chiral Compounds

“…38 Commercial GC CSPs still play a major role in developing available analytical methods for significant chiral compounds. 40 Terpenoid enantiomers exhibit great difference in odor. Chandan et al 41 developed a simple and sensitive chiral GC method for terpenoid enantiomers with various commercial CD-based CSPs, including 2,3-disubstituted ethyl-and acetyl-CD, and permethylated CD.…”

Region of interest selection in heterogeneous digital image: Wine age prediction by comprehensive two-dimensional gas chromatography

“…The outcomes of this study point to a generally similar content of naphthalene across all the samples data. The results obtained align with previous research findings ( Furdíková et al, 2019 ; Furdíková et al, 2020 ; Khvalbota et al, 2021 ; Machyňáková et al, 2021 ; Vyviurska et 2021 ; Vyviurska et al, 2022 ). Compounds such as ethyl octanoate, benzaldehyde, butyl ethyl succinate, β-phenethyl acetate, and sorbic acid were detected in all samples ( Table 2 S).…”
