“…The interday RSDs (n = 3) were in the range of 4.2–5.6% for malathion and 5.1–6.1% for diazinon. The EF was evaluated as the ratio of the peak areas for the concentrations of analytes in the eluent solvent (C e ) to the primary concentration of the analytes in the aqueous sample (C 0 ) ( Ghani et al, 2021 ). The results have been reported in the Supplementary information ( Table S10 ).…”
