CPSC Phthalate SOP

This document provides test methods for analyzing phthalate content in children's products used by the U.S. Consumer Product Safety Commission (CPSC). It describes sample preparation, phthalate extraction, gas chromatography-mass spectrometry operating procedures, quality control measures, and calculations for determining phthalate concentration. Comments on the methods are encouraged by March 31, 2009. The general approach is to grind samples, dissolve in solvents, filter, dilute, and analyze by GC-MS, integrating peak areas to quantify six regulated phthalates.
