National Dioxin Study: Analytical Procedures and Quality Assurance Plan for the Analysis of 2,3,7,8-TCDD in Tier 3-7 Samples of the U.S. Environmental Protection Agency National Dioxin Strategy

摘要

Analytical methodology used by EMSL-RTP, ECL-BSL and ERL-D in the analysis of samples for the study of Tiers 3-7 in the U.S. EPA National Dioxin Strategy is provided. The methods are based on low and high resolution mass spectrometry using stable isotope labeled internal standards. The methods were peer reviewed by the Quality Assurance Committee for the National Dioxin Strategy, as revised in November 1984. The methods are to serve only as a guideline for these analyses and may be modified as required to successfully meet target detection limits.
