This standard is applicable to the determination of trimethylamine in the exhaust gas of odor pollution sources and the ambient air of factories. When the sampling volume is 10L, the minimum detectable concentration of the method is 2.5-3 × 10mg/m3. This standard determines the presence of trimethylamine in a gaseous state. The 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 in this method.

Determination of Methanol in Exhaust from Fixed Pollution Sources by Gas Chromatography
Determination of methanol in exhaust gas from fixed pollution sources by gas chromatography. Detailed information:
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has proposed through extensive research and experimentation that "methanol in the air, after being absorbed by water, is suitable for the determination of methanol in environmental air and industrial pollution source emissions. The detection limit of the method is 0.5 μ g/5ml, and 30L of air is collected at a flow rate of 0.5L/min, with a minimum detection concentration of 0.016mg/m3. This method clearly demonstrates the advantages of "fast speed, easy operation, high sensitivity and accuracy, good reproducibility, and wide linear range" compared to current testing methods.
