Appendix D Certificate of analysis
The Institute for Reference Materials and Measurements in Belgium provides European reference Materials just like the National Institute of Standards and Technology (NIST) does in the US. In this study we have used two of the polymer samples (polyethylene) to calibrate the Bromine analysis carried out with the XRF analyser. These standards were provided by Sietronics Pty Ltd located in Canberra, Australia. Despite being past their validity date we have assumed the standards consisting of plastic granules enclosed in a Nylon / Mylar housing would not lose their bromine contents.
