Part 1: An NO standard containing 100 mL/m3 is to be used to calibrate an analyzer. If the flow from the standard tank is set to 200 mL/min, and the flow of zero air is 300 mL/min, what concentration of NO is produced? Part 2: The analyzer gives a reading of 40.0 mL/m3 for NOx when the above standard is passed through it. When the ozone generator in the dilution system is turned on, the NO reading drops and the NOx reading is 39.2 mL/m3. What is the efficiency of the converter?
