Table B-3 to Subpart B of Part 53 —Interferent Test Concentration,1 Parts per Million
Pollutant Analyzer type Hydro-chloric acid Ammonia Hydrogensulfide Sulfur dioxide Nitrogen dioxide Nitric oxide Carbon dioxide Ethylene Ozone Mxy-lene Water vapor Carbon monoxide Methane Ethane Naphthalene
1 Concentrations of interferent listed must be prepared and controlled to ±10 percent of the stated value.
2 Analyzer types not listed will be considered by the Administrator as special cases.
3 Do not mix with the pollutant.
4 Concentration of pollutant used for test. These pollutant concentrations must be prepared to ±10 percent of the stated value.
5 If candidate method utilizes an elevated-temperature scrubber for removal of aromatic hydrocarbons, perform this interference test.
6 If naphthalene test concentration cannot be accurately quantified, remove the scrubber, use a test concentration that causes a full scale response, reattach the scrubber, and evaluate response for interference.
