Gas Chromatography/Mass Spec (GC/MS)


Lipid and fatty acid analysis using state-of-the-art gas chromatography

4 December 2018 | By Agilent Technologies

The characterisation of lipids is one of the major applications of gas chromatography in food analysis. In general, GC can be applied to the analysis of intact lipids, such as triglycerides, or to the analysis of the fatty acid composition based on fatty acid methyl ester (FAME) profiling. A broad…

Aroma and Flavour analysis in Food and Beverage Samples

25 September 2018 | By Agilent

The flavour and aroma of food and beverages is key for perception and acceptance by the consumer. Gas Chromatography with Mass Spec detection is an effective tool to determine most of the key compounds involved and is finding increased adoption in recent years due to new techniques in sampling the…

Analysis of aroma compounds in edible oils by direct Thermal Desorption GC/MS using slitted microvials

9 July 2018 | By

The determination of aroma compounds in edible oils (olive oil, sunflower oil, fish oil etc.) is important for manufacturers and vendors of these products. Especially off-flavors / off-flavours derived from unsaturated fatty acid degradation such as, for example, hexanal, 2-(E)-nonenal and 2,4-(E,E)-decadienal are of interest. These compounds can compromise the…

Fully automated determination of 3-MCPD and Glycidol in edible oils by GC/MS based on the commonly used methods ISO 18363-1, AOCS Cd 29c-13, and DGF C-VI 18 (10)

9 July 2018 | By

3-MCPD and Glycidol and especially their fatty acid esters are process contaminants that are formed, for example, when edible oils and fats are refined. At least some of the above-mentioned substances are classified as potential human carcinogens, a fact which has prompted the introduction of rules and regulations that specify…

Maximising mass spectrometry capabilities in food analyses for multiresidues

6 February 2018 | By Waters

About this webinar Routine testing laboratories continue to strive for efficient and reliable sample throughput. Multiresidue pesticides is an example of this, where the generic extraction offered by QuEChERS has streamlined sample preparation. However, for comprehensive pesticide testing, both liquid and gas chromatography are typically required. During this webinar, Waters…
