Passivation and Electroplating [Texas] 

++

I work in Metal finishing and electroplating facility. We perform electroless Nickel plating, and stainless steel passivation with sodium dichromate chemistry.

How can I test for the presence of dichromate on the surface of a piece of stainless steel after passivation?
