4%PEG-20M+1%KOH/GDX-401，， 环境空气中三甲胺测定不锈钢填充柱的详细资料

环境空气中三甲胺测定不锈钢填充柱
环境空气中三甲胺测定不锈钢填充柱 详细信息：

浩瀚色谱（山东）应用技术开发有限公司采用4%聚乙二醇(PEG)-20M+1%KOHGXD-401为固定相,2m×3mm玻璃填充柱分离三甲胺,FID检测。该方法有较高灵敏度和良好的线性关系。结果表明:在柱温140℃,进样口温度180℃,检测器温度180℃,氮流量30mL/min时,平均回收率为100 3%,相对标准差为3%。

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。
