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 MOREApp Note 188/2016 An automated analysis system consisting of a dynamic headspace (DHS) system coupled with thermal desorption-Gas Chromatography/ Mass Spectrometry (TD-GC/MS) was used for fully automated micro-scale chamber material […]
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 MORE1,4-Dioxane is a chemical contaminant formed in trace amounts as a byproduct during the manufacturing process of detergents, foaming agents, emulsifiers and some solvents, which are widely used ingredients of […]
LEARN MOREIn this study, the GERSTEL PYRO was used for the pyrolysis of various materials that are relevant to forensic analysis applications, including paints, adhesives, and cosmetics. A GERSTEL MultiPurpose Sampler […]
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 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 […]
LEARN MORE218/2021 In this study, Thin Film Solid Phase Microextraction (TF-SPME) with a divinylbenzene/polydimethylsiloxane coating (DVB/PDMS) was used to extract off-odor compounds from paper product samples. The use of gas chromatography-mass […]
