Performance Test Results and Comparative Data for Designated Reference Methods for Nitrogen Dioxide

摘要

The U.S. Environmental Protection Agency designates specific ambient monitoring methods and analyzers as reference or equivalent methods acceptable for use in certain required monitoring. Such designation is based on performance testing of the analyzer model by the manufacturer (or other applicant) prior to designation. After designation, EPA carries out further tests to evaluate the performance, reliability, and operational peculiarities of the analyzer with respect to other analyzers monitoring the same pollutant. This report summarizes both the manufacturer's predesignation test results and the available EPA postdesignation test results for currently designated Nitrogen dioxide analyzers.
