SPE and GC-ECD Pesticide Analysis in Bee Product
A research group from Aristotle University of Thessaloniki (Thesaloniki, Greece) analyzed royal jelly, an important bee product, fortified with nine pesticides.
A research group from Aristotle University of Thessaloniki (Thesaloniki, Greece) analyzed royal jelly, an important bee product, fortified with nine pesticides. They used a technique consisting of solid-phase extraction (SPE) with a C18 cartridge followed by analysis with gas chromatography with micro-electron-capture detection (GC–ECD). The analytes were four synthetic acaricides used by beekeepers along with one pyrethroid, two organochlorine, and two organophosphate insecticides. The limits of quantification were 0.003–0.005 mg/kg, and the reporting level (lowest recovery level) was 0.005 mg/kg.
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>.
