Colorimetric powder identification?

Hey SM!

I got a box of different colorimetric powders, and because of some pretty color changes I wanted to keep them, despite the fact, that I probably won't have a real need for them.

I tried to search for exact indicators/substances in them, but lost my patience with no luck. They come from 1979, soviet Russia. the ampules are all labeled with what it is used for and date of ampuling and there are cards with information of detectable quantities ant time required.

Are these mixtures of substances/ indicator covered inert particles or is it possible to find out what each ampule contains?

Thanks!
