Analysis of Bisphenol-A by EPA Method 625

Bisphenol A, (http://en.wikipedia.org/wiki/Bisphenol_A) as one of the EPA's emerging pollutants is of interest to both the public and private sectors. Commonly utilized in plastics manufacturing, it has been identified as an endocrine disruptor impacting gender differentiation in some aquatic organisms and increasing concerns regarding human exposure as well.

To support these parties, Suburban Laboratories has developed and validated the a GCMS analytical procedure for trace level analysis of the compound in aqueous samples. The method is based upon USEPA EPA Method 625 (http://www.epa.gov/waterscience/methods/method/organics/625.pdf). The validation was performed following EPA protocols (40CFR Part 136, Appendix B).

Based upon the study the laboratory will utilize a reporting limit of 1 ug/L. The actual MDL from the study was found to be 0.32 ug/L.
