Hao Han Chromatography established and optimized a method for the determination of triethylamine in workplace air using capillary chromatography column solvent resolution gas chromatography. The method uses an alkaline silica gel tube to collect triethylamine in the workplace, adds sulfuric acid and sodium hydroxide for resolution, uses HH-1 chromatography column for separation, and uses FID for determination. Results The detection limit of triethylamine in this method is 0.5 μg/ml, the linear range is 0.5~1 340.0 μg/ml, the lowest detection concentration is 0.13 mg/m3 (based on collecting 7.5 L of air samples); the relative standard deviation is 0.63%~3.31%, the resolution efficiency is 99.5%~100.6%, the spiked recovery is 98.2%~101.8%, and the sample can be stored at room temperature for at least 7 days. Conclusion This method is suitable for the determination of triethylamine in workplace air.
This standard specifies the gas chromatography method for determining triethylamine in exhaust gas from stationary pollution sources.
This standard is applicable to the determination of triethylamine concentration in the organized and unorganized emissions of fixed pollution sources.
In the monitoring of organized and unorganized emissions, the detection limit of the method is 0.15 mg/m3 when the sampling volume is 10 L (standard state), and the detection limit of the method is 0.05 mg/m3 when the sampling volume is 30 L (standard state).
