Gas Chromatographic Fingerprint Analysis for the Comparison of Seized Cannabis Samples.
Publication Type: Academic Journal
Source(s): Molecules (Basel, Switzerland) [Molecules] 2021 Nov 02; Vol. 26 (21). Date of Electronic Publication: 2021 Nov 02.
Abstract: Cannabis sativa L. is widely used as recreational illegal drugs. Illicit Cannabis profiling, comparing seized samples, is challenging due to natural Cannabis heterogeneity. The aim of this study was to use GC-FID and GC-MS herbal fingerprints for intra...
Study on Gas Chromatographic Fingerprint of Essential Oil from Stellera chamaejasme Flowers and Its Repellent Activities against Three Stored Product Insects.
Publication Type: Academic Journal
Source(s): Molecules (Basel, Switzerland) [Molecules] 2021 Oct 25; Vol. 26 (21). Date of Electronic Publication: 2021 Oct 25.
Abstract: The objective of this study was to establish the chromatographic fingerprints of the essential oil (EO) from Stellera chamaejasme flowers collected from various natural sites by gas chromatography (GC) combined with chemometric methods. The EO was obta...
Recent update of the various sources originating ghost peaks in gas chromatography: A review.
Publication Type: Academic Journal
Source(s): Journal of chromatography. A [J Chromatogr A] 2022 Dec 06; Vol. 1685, pp. 463625. Date of Electronic Publication: 2022 Oct 30.
Abstract: Gas chromatography (GC) is a versatile tool for separating various volatile, semi-volatile, and thermally stable compounds. However, the ghost peaks in the GC are now a major concern for chromatographic analysts. Ghost peaks may interfere with the anal...
Planar Elongated B 12 Structure in M 3 B 12 Clusters (M = Cu-Au).
Publication Type: Academic Journal
Source(s): Molecules (Basel, Switzerland) [Molecules] 2022 Dec 28; Vol. 28 (1). Date of Electronic Publication: 2022 Dec 28.
Abstract: Here, it is shown that the M 3 B 12 (M = Cu-Au) clusters' global minima consist of an elongated planar B 12 fragment connected by an in-plane linear M 3 fragment. This result is striking since this B 12 planar structure is not favored in the bare clust...
Evaluation of Cryogen-Free Thermal Modulation-Based Enantioselective Comprehensive Two-Dimensional Gas Chromatography for Stereo-Differentiation of Monoterpenes in Citrus spp. Leaf Oils.
Publication Type: Academic Journal
Source(s): Molecules (Basel, Switzerland) [Molecules] 2023 Feb 01; Vol. 28 (3). Date of Electronic Publication: 2023 Feb 01.
Abstract: This study evaluates the applicability of enantioselective gas chromatography ( e GC) and enantioselective comprehensive two-dimensional gas chromatography ( e GC×GC) coupled with flame ionization detection for the stereospecific analysis of designated...
Multidimensional Gas Chromatography of Organosulfur Compounds in Coffee and Structure-Odor Analysis of 2-Methyltetrahydrothiophen-3-one.
Publication Type: Academic Journal
Source(s): Journal of agricultural and food chemistry [J Agric Food Chem] 2023 Mar 15; Vol. 71 (10), pp. 4337-4345. Date of Electronic Publication: 2023 Mar 02.
Abstract: Organosulfur compounds (OSCs) in coffee remain challenging to analyze by conventional gas chromatography (GC) due to their low concentrations amid coffee's complex matrix and susceptibility to chiral-odor influences. In this study, multidimensional GC ...
Development and validation of headspace Solid-Phase microextraction coupled with gas chromatography (HS-SPME-GC) method for the analysis of zingiber zerumbet L.
