Dan, You would need to ask the supplier of your ferric oxalate for the
concentration that they put in your "B". It may vary from supplier to
supplier. If you are not currently using Pot.Chl. as a contrast agent (no B)
than, start with .3 grams/25ml water. This may change if you use primarily
platinum or palladium. This is just a starting point. You can adjust it and
it will also depend how accurate your scale is. You may wish to make larger
solution to start with, say 100ml and 1.2 grams. It will decompose over time,
so you'll need to determine, cost and time involved for your working style.
