Substitute for Nitric Acid Passivation

2004

Dear Sir/ Madam,

I am working in Quality Assurance dept. with manufacturing of Large Volume Parenterals in multinational organisation using stainless still equipments.

I fear about the use of nitric acid for passivation over a prolonged period say, about 8 years & hence would like to know / use any substitute for the same with detailed specifications.

Thanks & best regards,

Vijay Vasant Kshirsagar
