The Importance of Being Inert
The increasing need for even more sensitive analyses of harmful substances brings new pressure on gas chromatography (GC) analytical methods.
The increasing need for even more sensitive analyses of harmful substances brings new pressure on gas chromatography (GC) analytical methods. Flow path inertness is the next frontier in the continuous improvement of GC analyses. The ongoing development of ultra-inert inlets, columns and detectors - alongside test mixes and procedures that assure a highly inert flow path - is improving the ability to analyse difficult, active compounds present in trace amounts.
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>.
