Validation of gas chromatography for the determination of 10 chlorobenzenes in waste gas
In order to ensure the accuracy of the inspection results,unify the operating methods,and verify the existing test conditions(including instruments,equipment personnel,and environment),activated carbon adsorption/carbon disulfide desorption was used,and gas chromatography was used for FID detector analysis.Qualitative analysis was conducted based on the retention time peak area,and external standard method was used for quantitative analysis of 10 chlorobenzene compounds in fixed pollution sources.Indicating that 10 chlorobenzenes are present in the range of 1.0 to 50.0 μ g/mL.The linear relationship within the concentration range of g/mL is good,and the detection limit detected in the laboratory is less than or equal to the detection limit specified by the method.The detection limit and lower limit of the laboratory method meet the requirements of the standard method.The accuracy and repeatability of the test results for samples with high,medium,and low concentration levels were suitable for the current detection requirements of chlorobenzenes in the laboratory.
