In patent US5376510 from Ilford Limited I was found next formula:
Na5DTPA 37% 35ml (=13g)
Sodium sulfite 120g
Potassium carbonate 150g
Dimezone S 2.5g
Potassium bromide 7g
Sodium hydroxide 67% 12ml (=8g)
Total volume of solution isn't specified in patent. I think that its will be in range 950..1000ml.
Is this Ilford PQ Universal formula? Multigrade? or something else?
