Streamlined method for pesticide residues in high-lipid food samples
26 Mar 2020Complex samples that are high in lipid content pose one of the greatest challenges in pesticide residue analysis. In this application note, UCT outlines the performance benefits achieved using the new LipiFiltr® cartridge in applications involving multi-class, multi-residue analysis for a wide range of pesticides in complex, high-fat samples.

SpinFiltr
UCT, Inc.The latest addition to UCT’s QuEChERS line puts a new “spin” on dSPE. SpinFiltr™ combines the practice of conventional dSPE with the added benefit of ultrafiltration. UCT’s new format of dSPE salts paired with a 0.2µm filtration device, simultaneously removes unwanted matrix compounds and filters samples without the need for any additional steps. With traditional dSPE, analysts must pay close attention when removing the purified extracts from tubes as to not disrupt the layers formed during centrifugation. SpinFiltr™ not only eliminates this problem, but also allows analysts to recover additional sample without the salts getting in the way! Simply: Add Vortex Spin Salts and unwanted matrix stay in the top chamber while purified extract is filtered and collected in the bottom portion of the tube. The chamber is discarded and analysts are left with only purified extract that is ready for analysis.
