Fully automated quantitative determination of residual solvents in hemp oil performed by full evaporation headspace GC/MS without sample preparation.
Application Note: enhancing the performance of SPME and sorptive extraction for GC–MS using trap-based preconcentration
This study shows how GC–MS performance for the sampling of aroma compounds and off-odours in beverages can be enhanced by using techniques incorporating trap-based preconcentration.
Dr Colin Hamlet discusses the results of a study that identified constituent amounts of N-nitroso compounds in a range of foods and process available to the UK's retail market.
Mineral oil residues in food gain a lot of public concern in there recent years. No matter if talking about rice, noodles, olive oil or chocolate, there are numerous examples of mineral oil contaminations in food.
Determination of 208 pesticide residues and their metabolites in foods using Oasis PRiME HLB and Xevo TQ-GC
Gas chromatography-mass spectrometry (GC-MS) has been a common analytical method for pesticide measurement due to its high efficiency of separation, along with its qualitative and quantitative performance.

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
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)
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…
