### -M26A/CTM-033 sample train was modified using 6N caustic in the caustic impinger, in order to keep final sample

pH > 12, method requirement. The sample volumes are corrected for the CO2 concentration; due to the use of the strong caustic CO2 is removed from the gas stream. - Please also note that the values presented in this database and the values in the hard copy report will vary slightly. We expect these differences are due to the fact that the ERT database recalculates all values. -Testing was conducted prior to the EPA FAQs page being updated, therefore, the reduced sample time and increased caustic strength and volume significantly raised the method detection limit for the CTM-033 component.
