2.Turn on and adjust the O3 generator in the calibrator to produce sufficient O3 to decrease the NO concentration to about 10% of full scale. This will be equivalent to 80% of the URL of the NO2 channel. After the analyzer responses stabilize, record the resultant NO, NOx, and NO2 concentrations.

MOLY CONVERTER EFFICIENCY

IF THE NOX READING SHOULD DROP TO LESS THAN 96% OF ITS STARTING VALUE DURING THIS STEP, IT INDICATES THE MOLY CONVERTER IS IN NEED OF TROUBLESHOOTING OR REPLACEMENT. SEE SECTION 7.6.6 FOR FURTHER DETAILS.

3.While maintaining all other conditions, adjust the ozone generator to obtain several other concentrations of NO2 evenly spaced between the 80% URL point and the zero point. Record the NO, NOx, and NO2 concentrations for each additional point.

4.Calculate the resulting NO2 concentrations as follows:

[ NO2 ]OUT

= [NO ]ORIG

- [NO ]REM

Where:

[NO]ORIG is the NO concentration before the GPT ozone is turned on, and [NO]REM is the NO remaining after GPT.

5.Plot the NO2 concentration output by the instrument on the y-axis against the generated

NO2 [NO2]OUT on the x-axis. The plot should be a straight line within the ± 2% linearity criteria given for the NOx and NO channels. If the plot is not linear the most likely cause is that the converter needs replacing. See Section 7.6.6 on Moly converter efficiency.
