Vinaykumar,

Please don't shout.

Any commercial analytical laboratory equipped with either atomic absorption (AAS) ⇦this on eBay or Amazon [affil links] or inductively coupled plasma (ICP) spectrometers ⇦this on eBay affil links] can do it.

Dear Mr.Vinaykumar,
Copper in silver nitrate solution analysis is not simple analysis. This you can't do normal titration method. But, you can do by AAS or ICP method.

I agree with Vinaykumar,that you have to check the copper contents using the AAS or ICP in ppm
