Applied Technical Services (ATS) has established a detection limit of 0.1 parts per billion (ppb) to test for the presence of Bisphenol A (BPA) in various products. This is important to note because this unmatched capability can help your company achieve compliance with various state laws, and one in particular that has established a very low limit for BPA. Specifically, on July 1, 2013 the Toxin-Free Infants and Toddlers Act will go into effect in the state of California. The act establishes an allowable limit for BPA in bottles or cups intended for use by children three years of age or younger. The current California limit for BPA is 0.1 parts per billion (ppb). The main concern of manufacturers, sellers, and distributors of products affected by this regulation is finding a testing laboratory that can perform analysis for BPA to the low limit. ATS has indeed established a method to test down to these ultra-low levels. The instrumentation our lab uses to detect BPA with a detection limit of 100 ppt (which is equivalent to 0.1 ppb) is the Triple Quad Liquid Chromatography Mass-Spectrometer (LC/MS/MS). Testing to this extremely low detection limit will ensure your company is in compliance with the California limit.
