This experiment encompassed analyzing water samples for Bisphenol A (BP A) from polycarbonate containers with Solid Phase Microextraction (SPME). Standards were used, ranging in concentration from Oppb-lOOppm. Analyses were completed on the gas chromatograph coupled to a mass spectrometer detector using the selected ion monitoring (SIM) mode. SPME was effective as a technique for screening for BPA in water samples stored in polycarbonate containers. Concentrations of standards as low as 1 ppb were detected by GCMS SIM mode. BPA in water bottle samples ranged from 0- .76ppb as determined by a calibration curve generated from standards. The calibration curves showed a consistent logarithmic response with respect to concentration when samples were analyzed in SIM mode. It was concluded that SPME provided a good method for detecting BPA. Other techniques that should be explored are use of standard addition and spiking samples.
