haohan空气质量 三甲胺的测定4%PEG-20M+1%KOH/GDX-401填充柱3m*3mm，60-80目

本标准规定了环境空气、恶臭固定污染源有组织和无组织排放中三甲胺的气 相色谱测定法。

本标准适用于环境空气、恶臭固定污染源有组织和无组织排放中三甲胺的测 定。当采样体积为 10L 时，方法*低测定浓度为 2.5×10-3mg／m3 。
采用涂着草酸的玻璃微珠作为吸附剂，装填在采样管中，用于采集恶臭污染 源排气和厂界环境空气中的三甲胺。通过向采样管中注入饱和氢氧化钠溶液和氮 气，使采集的三甲胺游离成气态，直接用填充柱气相色谱法进行测定。

This standard specifies the gas chromatography method for the determination of trimethylamine in organized and unorganized emissions from environmental air and odor fixed pollution sources.
This standard is applicable to the determination of trimethylamine in organized and unorganized emissions from environmental air and odor fixed pollution sources. When the sampling volume is 10L, the minimum measured concentration of the method is 2.5 × 10-3mg/m3.
Glass microspheres coated with oxalic acid are used as adsorbents and loaded into sampling tubes to collect trimethylamine from odor pollution source exhaust and factory ambient air. By injecting saturated sodium hydroxide solution and nitrogen into the sampling tube, the collected trimethylamine is ionized into a gaseous state and directly measured by packed column gas chromatography.
