THMs and PCBs were separated and analysed with elution on Novapak ODS or μ-Bondapak phenyl column by an eluent containing p-nitrophenol (p-NP). THMs studied were CHCl3, CHBrCl2, CHBr2Cl, and CHBr3, and PCBs used were Aroclor 1221, 1242, 1248, α- and β-BHC. It was thought that the retention on the stationary phase and sensitivities of the samples are related to the interaction between the sample and stationary phase or p-NP. THMs were separated completely on the ODS column by elution with MeOH-water (30 : 70) containing 10×10^-4 M p-NP and some of PCBs were separated on the phenyl column by elution with CH3CN-water(50 : 50) containing 10×10^-4 M p-NP. Detection limits of THMs were from 10×10^-4 g to 10×10^-6 g. Aroclors were 2×10^-6 g, and α- and β-BHC were 2×10^-4 g and 10×10^-4 g respectively.
