Miniaturized gas chromatography (µGC) systems hold potential for the rapid analysis of volatile organic compounds (VOCs) in an extremely compact and low-power enabled platform. Here, we utilize microfabrication technology to demonstrate the single chip integration of the key components of a µGC ...
Recoveries were determined for five replicates at two spiking concentrations (0.050 and 0.100 mg kg⿿1). Matrix-matched standards at 0.025, 0.050, 0.100, 0.150, 0.250 mg kg⿿1 were for calibration. Results and discussion Extraction efficiency Generally, when dealing with the extraction of ...
Results and Discussion Extraction and enrichment of the flavor agents Since the content of flavor agents added in chewing gums is low, the extraction and enrichment of these trace flavor agents are the crucial steps before the selective and sensitive detection. Here, as an effective technique to ...

Gas chromatography remains the worlds most widely used analytical technique, yet the expertise of a large proportion of chromatographers lies in other fields. Many users have little real knowledge of the variablesin the chromatographic process, the interaction between those variables, how they are best...
With the advent of electrospray ionisation (ESI) and matrix-assisted laser desorption ionisation (MALDI), mass spectrometry (MS) is now routinely used to establish the molecular formulae of gold nanoclusters (AuNCs). ESI-MS has been used to monitor the s
Gas chromatography–mass spectrometry (GC-MS) is a technique frequently used in targeted and non-targeted measurements of metabolites. Most existing software tools for processing of raw instrument GC-MS data tightly integrate data processing methods with
Results and discussion Commercial EOs of P. sylvestris were obtained from the three registered suppliers for P. sylvestris EO (1–4, European Chemicals Agency [ECHA], Supplementary Information, Table A1)15 and local providers, respectively. In general, the chromatographic profile of a primary pine...
In the present work, a method based on solvent extraction and gas chromatography–mass spectrometry (GC-MS) has been validated for the determination of 1,4-dioxane in cosmetics. Various solvents including ethyl acetate, hexane, methanol, dichloromethane
