We improved our previous analytical method to measure phthalate metabolites in urine as biomarkers for phthalate exposure by automating the solid-phase extraction (SPE) procedure and expanding the analytical capability to quantify four additional metabolites: phthalic acid, mono-3-carboxypropyl phthalate, mono-isobutyl phthalate

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
