|Test instrument:||gas chromatograph|
|Sample quantity:||50 ml|
|Analysis for:||waste oil|
|Brief description:|| |
In some cases, waste oils, especially from insulating fluids in transformers and capacitors and from hydraulic oils in mining, may contain PCB's (polychlorinated biephenyls). These are to be regarded as a health hazard.
The determination is carried out with a gas chromatograph. The PCBs are separated from the oil on the column and 6 characteristic congeners are detected with an ECD (halogen-specific detector). The sum of these compounds is given as the result.
6 selected congeners are determined by gas chromatography.
The results are indicated in the analysis report:
The 6 congeners are:
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.
