Quality testing of phosphate conversion

2007

I'm writing a specification for Zinc-phosphate conversion of steel parts.
I'd like to have a quick test to assess the quality of the treatment. A real weight would be fine but hazardous chemicals we're not allowed to keep them in our lab. Any suggestion?
Thanks you.

Best Regards

I would suggest x-ray fluorescence.

Have you considered farming out the lab work to someone who is allowed to do lab work? A chemical lab that can't use chemicals is ridiculous :-)

I appreciate Terry's suggestion, but x-ray fluorescence involves radioactive chemicals.
