Qualification of Ambient Methods as Reference Methods

Source

A description is given of a measurement methods qualifications program used by the Environmental Protection Agency (EPA) in its reference methods activities. The first step of the two-step program is an in-depth evaluation of a method for the purpose of critically examining, in a single laboratory, a method to determine its strengths and weaknesses. The second step is an interlaboratory collaborative test of the method whereby the method is placed in the hands of typical users for the purpose of determining important statistics on precision and accuracy. The program for evaluating methodology for ambient nitrogen dioxide in support of EPA's replacement reference method is presented as an example of this process.
