Comparative study between SiliaFast FaPEx® and QuEChERS for pesticide analysis in green cabbage

> back to SiliaFast FaPEx Applications Notes

This study compares the SiliaFast™ FaPEx® and the QuEChERS® for pesticide analysis at different concentrations. SiliaFast™ FaPEx® show similar or higher recoveries for all tested pesticides and are a great alternative for pesticides acting as thermal stability indicators (Diafenthion and Ethoxyquin), which are often degraded with other methods.

« The present study demonstrates that the SiliaFast FaPEx sample preparation approach worked well for a variety of pesticides in green cabbage. As shown in Figures 1-3, average analyte recoveries are better using SiliaFast FaPEx than QuEChERS, with the added advantage of being method of choice for heat sensitive pesticides. Reproducibility, as determined by % RSD for n=3 replicates, is also excellent. Finally, as shown in Figure 4, SiliaFast FaPEx can be used at various concentrations without significant recovery variation. »
