6 selected congeners are determined by gas chromatography.
The results are indicated in the analysis report:
- according to DIN - as sum of the 6 measured values
- according to LAGA - as sum of the 6 measured values multiplied by 5
The 6 congeners are:
- PCB 28
- PCB 52
- PCB 101
- PCB 138
- PCB 153
- PCB 180
The limit value for PCBs according to paragraph 1 No. 3 of the PCB, PCT, VC Prohibition Ordinance is exceeded if the sum of the 6 PCBs according to DIN is greater than 11 mg/kg.
