App Note 185/2016 A full evaporation DHS (FEDHS) method, based on a classical full evaporation technique (FET) [1] was demonstrated for uniform enrichment of aroma compounds in several sample types […]
LEARN MOREIn this study, Thin Film Solid Phase Micro-Extraction (TF-SPME) devices with carboxen/ polydimethylsiloxane (CAR/PDMS), divinylbenzene/polydimethylsiloxane (DVB/PDMS), and hydrophilic lipophilic balanced/polydimethylsiloxane (HLB/ PDMS) coatings are investigated for their usefulness for beverage […]
LEARN MORE228/2021 Mineral oil hydrocarbon (MOH) contaminants can be found in foods such as cereals, baked goods, fats and oils, coffee and many more. MOH can be introduced through process aids, […]
LEARN MOREAs the cannabis market continues its seemingly exponential growth, there is an immediate need for testing the variety of cannabinoid containing sample types now available. Here we show that a […]
LEARN MORE223/2021 Gas Chromatography-Olfactometry (GC-O) is an essential technique in aroma analysis. Olfactory detection is often performed in parallel with GC detection, for example, using a mass spectrometer. To ensure that […]
LEARN MORE221/2021 Static headspace analysis is often considered to be useful only when the analytes of interest are present in high concentrations. Although techniques like solid phase microextraction (SPME) and dynamic […]
LEARN MORE2021/222 Liquid-liquid extractions are used to extract and concentrate analytes from aqueous matrices. This extraction technique is widely accepted as shown by its inclusion within many official methods. Analytical laboratories […]
LEARN MOREIn this Appbrief samples from fish tissue were extracted by Stir Bar Sorptive Extraction (SBSE) using a GERSTEL Twister®, followed by analysis using a GERSTEL MPS thermal desorption system for […]
LEARN MORE220/2021 Laboratory samples are typically extracted prior to analysis by sensitive GC-MS or LC-MS/MS methods to separate the analytes of interest from the bulk of matrix components that could interfere […]
