Improved Performance in Capillary GC Columns
The introduction of a new range of capillary GC columns substantially reduces column bleed, increases inertness and offers unparalleled injection-to-injection and batch-to-batch reproducibility.
The development of durable and inert stationary phases for GC has substantial benefits for the analysis of all compounds as it improves the sensitivity and reproducibility of the assay and increases the overall robustness of analysis. The introduction of a new range of capillary GC columns substantially reduces column bleed, increases inertness and offers unparalleled injection-to-injection and batch-to-batch reproducibility. The highly inert characteristics displayed, as well as the improved column performance, are outlined here in a series of tests and applications.
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.
