A very interesting read, PE, thanks. Just to make sure: MQ, that would be Metol-Quinol? Of all the things that acronymfinder comes up with, that sounds like the most plausible. So, that's just testing in a B&W developer?
I'm awaiting the next part with much interest .
Metol, Hydroquinone is the mix that gives the acronym MQ.
We, in the industry, have used that since just about forever.
Another is EAA (Elon, Ascorbic Acid) another acronym used rather universally.
