Performance of USEPA Method for Analysis of 2,3,7,8-Tetrachloro-Dibenzo-p-Dioxin in Soils and Sediments by Contractor Laboratories

Source

The United States Environmental Protection Agency's superfund contractor laboratories use the method found in USEPA IFB WA84-A002 to analyze soil and sediment samples for the specific isomer 2,3,7,8-tetrachloro-dibenzo-p-dioxin. This method uses isotope dilution gas chromatography and mass spectrometry (GC/MS). The precision, accuracy, detection limit, isomer specificity, recovery, and other performance parameters are important in evaluating performance of laboratories and methods. The observed performance of this method in the production-line analysis of thousands of samples by eleven contractor laboratories is presented in this paper.
