QuEChERS micro-SPE clean-up method for the determination of pesticides in feed samples in GC-orbitrap-based analysis-collaborative study

Activity: Talks and presentationsConference presentations

Description

To enhance precision and streamline sample preparation in routine analysis, many laboratories are adopting automation tools for sample clean-up. In 2022, the European Reference Laboratory for Pesticides in Cereals and Feedstuff (EURL-CF), in collaboration with CTC Analytics, developed and implemented a new fully automated clean-up workflow utilizing a Stand-Alone Multipurpose Autosampler. This automated procedure includes clean-up followed by dilution of the purified extract and addition of quality standards.
A collaborative study between EURL-CF and Wageningen Food Safety Research (WFSR) aimed to assess the performance of the QuEChERS-μSPE clean-up method using the stand-alone system across various feed samples. Comparisons were made between cartridges containing and not containing graphitized carbon black (GBC) in their sorbent composition. The usage of GCB visually showed a notable improvement in pigment removal, particularly in fish feed, likely due to the elimination of carotenoids such as astaxanthin.
