An on-line SPE-HPLC method for effective sample preconcentration and determination of fenoxycarb and cis, trans-permethrin in surface waters
Original language description
A new on-line SPE-HPLC method using fused-core columns for on-line solid phase extraction and large volume sample injection for increasing the sensitivity of detection was developed for the determination of insecticides fenoxycarb and cis-, trans-permethrin in surface waters. The separation was carried out on fused-core column Phenyl-Hexyl (100 x 4.6 mm), particle size 2.7 mu m with mobile phase acetonitrile: water in gradient mode at flow rate 1.0 mL min(-1), column temperature 45 degrees C. Large volume sample injection (1500 mu L) to the extraction dimension using short precolumn Ascentis Express RP C-18 (5 x 4.6 mm); fused-core particle size 2.7 mu m allowed effective sample preconcentration and efficient ballast sample matrix removal. The washingmobile phase consisting of a mixture of acetonitrile:water; 30:70, (v/v) was pumped at flow rate of 0.5 mL min(-1) through the extraction precolumn to the waste.
