Recent progress in food flavor analysis using gas chromatography-ion mobility spectrometry (GC-IMS).
Food Chemistry, 2020Rapid, nondestructive, high-throughput testing and screening of volatile ingredients plays an important role in food flavor analysis. Gas chromatography-ion mobility spectrometry (GC-IMS) is a powerful technique for the separation and sensitive detection

This review of the fundamental developments in gas chromatography (GC) includes articles published from 1996 and 1997 and an occasional citation prior to 1996. The literature was reviewed principally using CA Selects for Gas Chromatography from Chemical Abstracts Service, and some significant articles from late 1997 may be missing from the review.

Ion mobility spectrometry coupled to gas chromatography: A rapid tool to assess eggs freshness.
Food Chemistry, 2019Egg products freshness is a crucial problem for the production of safe and high quality food. Ion Mobility Spectrometry (IMS) coupled to Gas Chromatography (GC), provides a rapid, sensitive, cost-effective tool for the detection of freshness issues.

To determine the key aroma compounds in Chinese rice wine (CRW), four types of CRW (YH, JF, SN, and XX) were analyzed by gas chromatography-mass spectrometry (GC-MS), gas chromatography-olfactometry (GC-O), and sensory evaluation.

Japanese green tea is becoming increasingly popular worldwide due to its pleasant aroma. The volatiles of four types of Japanese green tea (Sencha, Matcha, Gyokuro, and Hojicha) were extracted separately by headspace solid-phase microextraction (HS-SPME)

Continuous gas chromatography has been achieved with a radial-flow chromatographic channel free of packing and formed between two closely spaced (50 to 75 microns) disc surfaces (optically flat and solvent-coated) rotating at one-half or one revolution per second. This technique provides high capacity and immediate response (in a fraction of a second).

Turbulent flow in gas chromatography was achieved and its effect was studied with high-speed, high-pressure equipment. A gas-solid capillary and several packed columns were used. The onset of turbulence was associated with abrupt decrease in peak width in the capillary and gradual leveling off and decrease in the packed columns.

Overview All forms of chromatography separate components of a mixture by taking advantage of the fact that each component has a different affinity for a particular media. Both liquid and gas chromatographs use this principle and employ two different media—a sorbent-packed column and a solvent (termed the stationary phase and the mobile phase)—to ...
