31/7/2014 · Ultraperformance liquid chromatography mass spectrometry (UPLC-MS), flow injection mass spectrometry (FIMS), and headspace gas chromatography (headspace-GC) combined with multivariate data analysis techniques were examined and compared in differentiating organically grown oregano from that grown conventionally. It is the first time that headspace-GC fingerprinting

8/4/2013 · A new detection method using headspace single-drop microextraction (HS-SDME) coupled to gas chromatography (GC) was established to determine the iodine in milk powder and urine. The derivative from the reaction between iodine and butanone in the acidic media was extracted into a micro-drop then determined by GC-ECD.

1/1/2002 · Chapter 10 Headspace gas chromatography Zelda E. Penton 10.1 OVERVIEW 10.1.1 Introduction Headspace gas chromatography (GC) is a sample preparation method for determining volatile compounds in solid and liquid samples. The technique has existed since the late 1950s [1] and is still actively used. The popularity of headspace analysis is due to

6/11/2017 · Headspace-Gas Chromatography (HS-GC) has been evaluated as a green alternative for the elimination, or at least the large reduction, of solvents in analytical determinations. The direct use of HS-GC and the pre-concentration of analytes in the HS vial offer fast, safe,

Basics & Fundamentals: Gas Chromatography Introduction Gas chromatography (GC) is an analytical methodology, which was devised by Nobel Laureate, Martin, et al. in 1952. More than 60 years after the award, GC systems are widely commercialized and

The headspace compounds of teleme cheese made from sheep's milk, goats’ milk or mixture of sheep's and goats’ milk (50:50) were analysed during ripening by static headspace gas chromatography

8/4/2013 · A new detection method using headspace single-drop microextraction (HS-SDME) coupled to gas chromatography (GC) was established to determine the iodine in milk powder and urine. The derivative from the reaction between iodine and butanone in the acidic media was extracted into a micro-drop then determined by GC-ECD. With the optimisation of HS-SDME and derivatisation, the calibration

Static headspace sampling technique coupled with gas chromatography and mass spectrometry was used to investigate the presence of volatile 2-alkyl-3-methoxypyrazines in three different species of ladybugs of the Coccinellidae family. The species investigated …

Headspace volatiles of freshly brewed drip coffee were investigated by gas chromatography/mass spectrometry (GC/MS) and gas chromatography/olfactometry (GC/O, CharmAnalysis) analyses. For this purpose, a solid-phase microextraction (SPME) sampling method for the headspace volatiles of freshly brewed drip coffee was developed.
