XRF Technologies for Measuring Trace Elements in Soil and Sediment: Niton XLi 700 Series XRF Analyzer. Innovative Technology Verification Report.

摘要

The Niton XLi 700 Series (XLi) XRF Services x-ray fluorescence (XRF) analyzer was demonstrated under the U.S. Environmental Protection Agency (EPA) Superfund Innovative Technology Evaluation (SITE) Program. The field portion of the demonstration was conducted in January 2005 at the Kennedy Athletic, Recreational and Social Park (KARS) at Kennedy Space Center on Merritt Island, Florida. The demonstration was designed to collect reliable performance and cost data for the XLi analyzer and seven other commercially available XRF instruments for measuring trace elements in soil and sediment. The performance and cost data were evaluated to document the relative performance of each XRF instrument. This innovative technology verification report describes the objectives and the results of that evaluation and serves to verify the performance and cost of the XLi analyzer. Separate reports have been prepared for the other XRF instruments that were evaluated as part of the demonstration.
