Description

Description

Analysis Note	Use of bisphenol A (BPA)-based plastics in food and beverage containers continues to be a point of controversy. This study demonstrates the solid phase micro extraction (SPME) of BPA from a fruit flavored energy drink using an overcoated PDMS/DVB fiber (overcoated with PDMS), followed by GC/MS/MS analysis using SLB-PAHms GC Column. At a 10 ppb spiking level, accuracy of the SPME method was 115% with an RSD of 1% for spiked replicates.
