| Abstract |
This report presents the results obtained from a collaborative test of Method 7 promulgated by EPA for determining the nitrogen oxide emissions from stationary sources. Method 7 specifies the collection of a grab sample in an evacuated flask containing a dilute sulfuric acid-hydrogen peroxide absorbing solution and the colorimetric measurement of the nitrogen oxides, except nitrous oxide, using the phenoldisulfonic acid procedure. The test was conducted at a nitric acid plant using 4 collaborating laboratories. The concentrations determined by the collaborators from all three phases of the test were submitted to statistical analysis to obtain estimates of the accuracy and precision that can be expected with the use of Method 7. |
