I just joined this forum and would really appreicate your help here.

What are the concentrations of the sulfuric and nitric acids you use for
wet chemical decapsulation. I'm in the process of purchasing chemicals for our chemical lab and need to know the concentration of acid in the solution that will yield the best results. I was thinking 90% Nitric Acid and 96% sulfuric acid would be ok to use but need you to confirm.

thank you

There are several variations of sulfuric and nitric acid on the market. Our equipment uses 20% fuming sulfuric and 98% fuming nitric. I could give you a few pointers if you would like to discuss further. erik@nisene.com or 831-761-7980
