Who can help in method development for the analysis of Pcbs in mineral oil by GC?

Call Supelco Technical Service
I believe they have the methodology to perform the analysis you desire.
Other companies may have similar methodologies but I cannot confirm this.

Also try either agilent or Restek.

I suspect the difficult part of this analysis is the isolation of the PCBs from the mineral oil.
Most companies have columns which will seaprate the different PCBs. The problem is looking at the levels of PCBs found in the sample matrix.
Mineral oil is very non polar much like the PCBs.
The EPA in the US, the JIP in Japan, and the European communities have different methods of isolation of PCBs.
These sources should be searched.

You might look at ASTM method D-4059,"Std test

Japanese Industrial Standard methods: JIS K 0311 and JIS K 0312 deal with the determination of dioxins and PCBs. The Japanese have also developed methods which measure PCBs in eggs and other food items.
Flash chromatography is used to isolate the PCBs and other solid phase columns are used to concentrate the analytes with minimal solvent use.
