- Scope
- This standard applies to the determination of trimethylamine in the exhaust of odor pollution sources and ambient air at the factory boundary. When the sampling volume was 10L, the minimum detection concentration of the method was 2.5-3×10mg/m3. This standard determines trimethylamine that exists in gaseous state. Amine compounds such as ammonia, methylamine, ethylamine, and dimethylamine in the sample do not interfere with the determination of trimethylamine under the chromatographic conditions selected by this method.
