Tom, When you are asking for a formula and then looking for a "standard" #
3, that suggest that you need to look at the seller of that product. There
is no standard #3 in my use of platinum chemistry. 

There is no A and B ferric, nor is there an NA2. 

What you want to do is make platinum solution using a different chemical
than the "standard" line is using. I was in fact told that telling people
that this alternative was bad for the industry. 

I am sure you'll find the solution to your quest by looking at Mike Ware's
site. I don't have it in front of me now. You'll be making a .7M solution. 

I'd be happy to post the formula, but I am away until the 20th.

Could someone provide the formula for platinum standard solution #3,  
using ammonium tetrachloroplatinate?

Many thanks,
