Application Note: Fully automated cryogen-free analysis of ethylene oxide and 2-chloroethanol in contaminated sesame seeds
7 February 2024

High levels of ethylene oxide (EtO) and 2-chloroethanol (2-CE) present in sesame seeds and other agricultural products have led to multiple product recalls throughout the EU. In this application note from Markes International Ltd., explore how headspace–trap with multi-step enrichment (MSE) on the Centri® platform has been used to quantitatively determine the contaminants at the required 0.05 mg/kg (50 ppb) reporting threshold or maximum residue limit (MRL) without extensive and manual sample preparation.
