||This verification test was conducted according to procedures specified in the peer-reviewed 'Test/QA Plan for Verification of Chemiluminescent Ozone Analyzer', and was carried out at Battelle laboratories in Columbus, Ohio from June 12 to June 28, 2007. The objective of this verification test was to evaluate the performance of the Optec 3.02 P-A, in part by comparing it to the response of the UV-absorption Federal Equivalent Method (FEM) for ozone. FEM's are established by EPA to assure high quality in ambient air monitoring data. The UV-absorption FEM for ozone is the method used for virtually all ambient ozone monitoring in the U.S. The specific commercial FEM monitor used in this test was the Thermo Environmental Model 49C (method EQOA-0880-047). Accuracy was determined by assessing the percent recovery of the 3.02 P-A with respect to different levels of ozone challenges. Linearity was assessed by a linear regression analysis using the ozone challenge concentration as the independent variable and the results from the 3.02 P-A as the dependent variable. The interference effects were calculated in terms of the ratio of the response when challenged with the interferent, to the actual concentration of the interferent. Comparability was assessed by comparing the 3.02 P-A response to that of the FEM in selected tests. Data completeness was assessed as the percentage of maximum data return achieved by the 3.02 P-A over the test period. Operational factors were evaluated by means of observations during testing and records of needed maintenance, vendor activities, and expendables use.
