Routine pesticide analysis using micro-SPE

The methodology of generic extraction with ethyl acetate is well established, but clean-up procedures are a major obstacle for the steadily increasing sample throughput due to the additional manual workload addressing separately the different kind of food commodities of a governmental laboratory. In this application note from CTC Analytics, explore the application of micro solid phase extraction (µSPE) for the clean-up of the raw extracts using ethyl acetate as extraction solvent for pesticides from different also more complex food commodities.
