Copper Content Detection in Ferric Chloride Etching Solution  

++

I will be very grateful to the person who can give me an idea about how to detect the amount of copper content in a Ferric Chloride Solution used for an etching process.

Any detection method will be fruitful to my investigation but if someone knows about a colorimetric way or a conductivity method then it will be the apongee.

Thanks in advance for any help.

Dear Sir,

We presently sell an colormetric instrument specifcally designed to determine the copper content of a etching ferric chloride solution.
