48. to calculate the efficiency of a Moly converter when using a GPT method of testing converters by using the US EPA method where the actual concentration of ozone is not a factor in the accuracy of the calculation of the converter efficiency This procedure is based on the Code of Federal Regulations Title 40 Chapter subchapter C Part 50 Appendix F TOOLS API M700 calibrator with O3 Gen option or equivalent PARTS NONE PROCEDURE Ts For the sake of numbers to input into this note we have chosen 450 PPB NO gas as our reference point you don t have to pick these values they are just an example There is also an assumption that the analyzer has a good calibration done 450 PPB NO span gas If this is not the case then once you are done with the leak check on the analyzer input your 450 PPB NO span gas and calibrate the analyzer NOTE for the GPT to be performed correctly there must be a minimum of 1096 MORE NO than OS produced For example if the Ozone produced is 400 PPB then the NO used must be 440 or more Typically 450 PPB NO is made and 400 PPB of Ozone is produced Leak check machine to ensure that there are no leaks in the analyzer If you have input a CE factor into the instrument firmware this would be in the CAL CONC CONV SET menu other than 10096 change this back to 10096 for the duration of this test The first gas check is to test to see how much the converter is eating NO gas or out gassing
