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.
