固定污染源废气中三甲胺测定安捷伦硬质玻璃柱
固定污染源废气中三甲胺测定安捷伦硬质玻璃柱 详细信息：

浩瀚色谱（山东）应用技术开发有限公司，建立了顶空-气相色谱法测定固定污染源废气中三甲胺的分析方法。弱酸性吸收液采集固定污染源废气中的三甲胺,碱液中和后顶空进样气相色谱FID检测器分析有组织废气中三甲胺进行检测分析,该方法能够满足国家标准及地方标准中三甲胺排放限值的要求。

本标准适用于恶臭污染源排气及厂界环境空气中三甲胺的测定。当采样体积为10L时，方法最低检出浓度为2.5-3×10mg/m3。 本标准测定以气体状态存在的三甲胺。 样品中的氨、甲胺、乙胺、二甲胺等胺类化合物在本方法选定的色谱条件下，均不干扰三甲胺的测定。

Determination of Trimethylamine in Waste Gas from Fixed Pollution Sources - Agilent Hard Glass Column
Determination of Trimethylamine in Fixed Source Waste Gas Agilent Hard Glass Column Details:
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established an analytical method for the determination of trimethylamine in waste gas from fixed pollution sources using headspace gas chromatography. The weakly acidic absorption solution is used to collect trimethylamine from fixed pollution source exhaust gas. After neutralization with alkaline solution, the headspace injection gas chromatography FID detector is used to analyze trimethylamine in organized exhaust gas for detection and analysis. This method can meet the requirements of national and local standards for trimethylamine emission limits.
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.
