Efficient Automated Pyrolysis GC
In this article, the authors describe a pyrolysis technique that is based on the injection of polymer emulsions or solutions using a high-temperature PTV system.
A novel approach for determining the structure and composition of polymers has been developed by scientists at Dow, a leading producer and supplier of chemicals and polymer products. In this article, the authors describe a pyrolysis technique that is based on the injection of polymer emulsions or solutions using a high-temperature PTV system. This approach enables efficient automation and improved determination of pyrolysis breakdown products using GC-FID or GC–MS.
RAFA 2024 Highlights: Contemporary Food Contamination Analysis Using Chromatography
November 18th 2024A series of lectures focusing on emerging analytical techniques used to analyse food contamination took place on Wednesday 6 November 2024 at RAFA 2024 in Prague, Czech Republic. The session included new approaches for analysing per- and polyfluoroalkyl substances (PFAS), polychlorinated alkanes (PCAS), Mineral Oil Hydrocarbons (MOH), and short- and medium-chain chlorinated paraffins (SCCPs and MCCPs).
Pharmaceutical excipients, such as polyethylene glycol-based polymers, must be tested for the presence of ethylene oxide (EtO) and 1,4-dioxane as part of a safety assessment, according to USP Chapter <228>.
Profiling Volatile Organic Compounds in Whisky with GC×GC–MS
November 1st 2024Researchers from Austria, Greece, and Italy conducted a study to analyze volatile organic compounds (VOCs) present in Irish and Scotch whiskys using solid-phase microextraction (SPME) Arrow with comprehensive two-dimensional gas chromatography coupled to mass spectrometry (GC×GC–MS) to examine the organoleptic characteristics that influence the taste of spirits.
