Hmmm.
Hearing that 2000ppm would be made this way.
Given that most dilute anysilver to 20ppm anyway I couldn’t personally see the point of making 2000ppm with any method !
I would presume that stabilisation would still be necessary so how would that be achieved?
Would that go in before or after your silver nitrate.
I can see that using a given, measured amount of compound would produce a known PPM but would particle size be controllable?
