The comparison of Supel™ QuE Z-Sep/C18, PSA/C18, and PSA QuEChERS sorbents, in terms of color removal and analyte recovery, is described for the cleanup of oranges prior to pesticide analysis.
Compared to conventional PSA/C18/GCB cleanup, cannabis extracts cleaned with the Supel QuE Verde mixture showed lower GC/MS background, and better recoveries for many pesticides.
