We developed an analytical method using off-line solid-phase extraction (SPE) coupled with on-line SPE and isotope-dilution high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) to determine the concentrations of phthalate metabolites in human meconium and in semen. First, we used off-line SPE
