1.1 This standard specifies the method of conducting qualitative and quantitative analysis to 2,3,7,8-chlorine-substituted PCDDs and PCDFs and tetrachloro~octachloro-substituted PCDDs and PCDFs by isotope dilution HRGC/HRMS.
1.2 This standard is applicable to the sampling, sample treatment and qualitative and quantitative analysis of PCDDs and PCDFs pollutants in the ambient air.
1.3 This standard is applicable to the sampling, sample treatment and qualitative and quantitative analysis of PCDDs and PCDFs pollutants in the stationary source emissions.
1.4 Detection limit of this method is dependent on various factors such as the sensitivity of the adopted analytical apparatus, concentration of PCDDs and PCDFs in the specimen as well as interference level. The detection limit of 2,3,7,8-T4CDD instrument shall be lower than 0.1pg. When the sampling amount of waste gas is 4m3 (standard condition), the minimum detection limit of 2,3,7,8-T4CDD instrument specified by this method shall be lower than 0.6 pg/m3; when the air sampling amount is 1000m3 (standard condition), its minimum detection limit specified by this method shall be lower than 0.003 pg/m3.
