posted on 2023-05-19, 02:33 authored by Wuethrich, A, Paul HaddadPaul Haddad, Joselito QuirinoThe synergistic stacking approach of field-enhanced sample injection-micelle-to-solvent stacking was used for high sensitivity CZE-ESI-MS of eight penicillins and sulfonamides. Sensitivity enhancement factors (peak height) were 1629-3328 compared to typical injection, with LODs from 0.11 to 0.55 ng/mL. The analytical figures of merit were acceptable. SPE on a fortified seawater sample resulted in 50-fold enrichment with recoveries of 85-110%. The overall method LODs were 0.002-0.011 ng/mL.
