浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司用涂著草酸的玻璃微珠為吸附劑、裝填玻璃采樣管,來采集大氣中的低級脂肪胺類化合物,再向采樣管中注入一定量的解吸試劑——飽和KOH溶液,使采集的胺類化合物被解吸并以氣態(tài)游離出來,與此同時通過一定量的氮氣將其趕入經(jīng)堿處理的小真空瓶中,然后從該瓶中取一定量樣品氣體直接注入色譜儀進行分析。選擇了裝有HH-Tamine60胺專用色譜柱及氫火焰離子化鑒定器,有效地分離定量了甲胺、二甲胺和三甲胺3種成分峰,在采樣體積為10 1時,本方法可對大氣中ppb級3種胺進行測定.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses oxalic acid-coated glass microbeads as adsorbents and fills glass sampling tubes to collect lower aliphatic amine compounds in the atmosphere, and then injects a certain amount of desorption reagents into the sampling tube— —Saturated KOH solution, so that the collected amine compounds are desorbed and released in gaseous state, and at the same time, they are driven into a small vacuum bottle treated with alkali through a certain amount of nitrogen, and then a certain amount of sample gas is taken from the bottle. Direct injection into the chromatograph for analysis. A special chromatographic column equipped with HH-Tamine60 amine and a hydrogen flame ionization identifier were selected to effectively separate and quantify three component peaks of methylamine, dimethylamine and trimethylamine. When the sampling volume was 10 1 , this method could be used for Determination of 3 amines at ppb level in the atmosphere.
