| Extraction Details |
An aliquot (20 mL) of filtered water sample was spiked with internal standards and then loaded onto an Oasis HLB Plus Light cartridge. The analytes retained in the cartridge were eluted with methanol/MTBE (3 mL, 7:3 v/v), and the eluate was concentrated to 0.2 mL under N2 flow. The residue was reconstituted in acetonitrile/methanol/Milli-Q water (1 mL, 1:2:7 v/v/v). For analysis of compounds found at concentrations >500 ng/L in water samples, the sample was diluted 2-fold prior to instrumental analysis. |
