Analysis of PCB in Transformer Oil
Meeting legal environmental requirements and certifications
PCB analysis detects the presence of polychlorinated biphenyls (PCB) in transformer oil samples. These toxic organic pollutants were used extensively in transformers for decades because of their ideal properties for use in transformers.
Accredited PCB ANALYSIS of Transformer oil
The use of PCBs has been restricted for many years and banned for use in new transformers. Nevertheless, large numbers of PCB-contaminated transformers are still in service. It is legally compulsory for industries and power plants to have the environmental and human risk determined by an accredited laboratory whenever a transformer is scrapped, maintained, displaced, sold or when an oil change takes place.
How to quantify the concentration of pcb in transformer oils?
We use gas chromatography equipped with an electron capture detector (GC-ECD) to quantify the concentration of PCB in transformer oil.
We employ several analytical test methods:
> IEC 61619 (Sum 109 congeners)
> EN 12766-2 (Sum 6 congeners)
> OVAM CMA/3/A
PCB Analyses (+ Required oil volume)
PCB (**) EN 12766-2 (Sum 6 congeners) 50 ml
PCB (**) IEC 61619 (Sum 109 congeners) 50 ml
PCB (**) OVAM CMA/3/A 50 ml
PCB (other matrices: sludge, waste, water, …)
(**): Analyses performed under ISO 17025 accreditation—Measurement uncertainties available on demand
Laborelec pcb measurement
There are 209 PCB congeners that differ by the number and position of the chlorine atom on the 2phenyl rings.
