测定固定污染源废气中挥发性有机物
测定固定污染源废气中挥发性有机物 详细信息：

名称：吸附管

规格：1/4*3.5
填料：200mg
形状：U，直管

型号：TENAX-TA

浩瀚色谱（山东）应用技术开发有限公司采用吸附管吸附-热脱附/气相色谱-质谱法,建立了废气中32种挥发性有机物的分析方法。在分析测定中,用HH-5毛细管色谱柱,采用全扫描方式,外标法定量。结果表明:在试验条件下,32种挥发性有机物线性回归方程相关系数均为0.998以上,方法检出限为0.31-2.64ng,以采样体积300mL计算,检出限为0.001-0.009mg/m~3,以空白样品为基体,进行加标回收率试验,高低浓度加标回收率在79.4%-128.1%之间,精密度在1.62%-14.84%之间,可满足日常废气中挥发性有机物的测定。

Determination of Volatile Organic Compounds in Waste Gas from Stationary Pollution Sources
Determination of volatile organic compounds in exhaust gas from stationary pollution sources Details:

Name: Adsorption tube

Specification: 1/4*3.5
Filler: 200mg
Shape: U, straight pipe

Model: TENAX-TA



Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses adsorption tube adsorption-thermal desorption/gas chromatography-mass spectrometry to establish an analysis method for 32 kinds of volatile organic compounds in exhaust gas. In the analysis and determination, the HH-5 capillary chromatographic column is used, the full scan method is adopted, and the external standard method is used for quantification. The results show that under the test conditions, the correlation coefficients of the linear regression equations for 32 kinds of volatile organic compounds are all above 0.998, and the detection limit of the method is 0.31-2.64ng, calculated with the sampling volume of 300mL, the detection limit is 0.001-0.009mg/m~ 3. Using the blank sample as the matrix, the standard addition recovery rate test is carried out. The high and low concentration addition recovery rate is between 79.4%-128.1%, and the precision is between 1.62%-14.84%, which can meet the requirements of volatile organic compounds in daily exhaust gas. Determination.
