HH-FFAP毛细管柱 工作场所空气中三种烷氧基乙醇化合物的同时测定法的详细资料

工作场所空气中三种烷氧基乙醇化合物的同时测定法
工作场所空气中三种烷氧基乙醇化合物的同时测定法 详细信息：

名称：毛细管柱

规格：30m*0.32mm*0.5um
型号：HH-FFAP

应用：工作场所空气有毒物质测定第50部分：2-甲氧基乙醇、2-乙氧基乙醇和2-丁氧基乙醇

浩瀚色谱（山东）应用技术开发有限公司建立了工作场所空气中2-甲氧基乙醇(EM),2-乙氧基乙醇(EE),2-丁氧基乙醇(EB)的溶剂解吸气相色谱同时测定法.采用活性炭管采集,溶剂解吸,毛细管色谱柱分离的气相色谱(FID)测定方法.EM,EE,EB在本方法规定的浓度范围内线性关系良好,相关系数均大于0.999,检出限均为0.50 mg/L,低检出浓度均为0.67 mg/m3(以采集3.0 L空气计).相对标准偏差(RSD)为0.4%～1.8%(n=6),平均解吸效率为97.3%～101.1%,样品在室温下少可保存7天.该方法灵敏度高,精密度好,操作简单,适用于工作场所空气中EM,EE,EB的同时测定.

Simultaneous determination of three alkoxyethanol compounds in workplace air
Simultaneous determination of three alkoxyethanol compounds in workplace air Details:

Name: capillary column

Specifications: 30m*0.32mm*0.5um
Model: HH-FFAP

Application: Determination of Toxic Substances in Workplace Air Part 50: 2-Methoxyethanol, 2-Ethoxyethanol and 2-Butoxyethanol

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established the solvent desorption gas chromatography of 2-methoxyethanol (EM), 2-ethoxyethanol (EE), 2-butoxyethanol (EB) in workplace air Simultaneous determination method. Using activated carbon tube collection, solvent desorption, and capillary chromatographic column separation gas chromatography (FID) determination method. EM, EE, EB have a good linear relationship within the concentration range specified by this method, and the correlation coefficients are all greater than 0.999. The limit of detection was 0.50 mg/L, and the lowest detection concentration was 0.67 mg/m3 (based on 3.0 L of air). The relative standard deviation (RSD) was 0.4%-1.8% (n=6), and the average desorption efficiency was 97.3 %～101.1%, the sample can be stored at room temperature for at least 7 days. The method has high sensitivity, good precision and simple operation, and is suitable for the simultaneous determination of EM, EE and EB in the air of the workplace.
