220/2021 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 MORE2021/219 In 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 MOREApp Note 196/2018 In the work presented here, highly sensitive determination of around 100 contaminants in surface water in the concentration range from low double digit to low triple-digit pg/L […]
LEARN MOREApp Note 213/2020 Stir Bar Sorptive Extraction (SBSE) coupled with gas chromatography-mass spectrometry and olfactory detection (GC-MS/O) allows for separation and identification of aroma compounds in complex sample matrices with […]
LEARN MOREApp Note 3/2000 2,4,6-Trichloroanisole (TCA) is well known as being the main cause for corkiness in wine. Its extremely low odor threshold usually mandates enrichment and concentration steps before it […]
LEARN MOREApp Note 2/2000 For the analysis of organic compounds in aqueous environmental matrices several sample preparation methods are used. Volatile organic compounds can be analyzed using (static) headspace, purge and […]
LEARN MOREApp Note 1/2000 A new approach using stir bars coated with PDMS was recently developed. In this approach, 50-300 μL PDMS coatings are used. Consequently, the sensitivity is increased by […]
LEARN MOREApp Note 2/2015 IV bag components were analyzed for extractables using direct thermal desorption/thermal extraction combined with a unit mass resolution GC/MSD system. The results were compared to those obtained […]
LEARN MOREApp Note 3/2002 The FDA requires that any food-contact materials that may reasonably be expected to migrate into food must conform to existing regulations or be included in a petition […]
