It's not cheap (and IIRC you have to use the whole lot in one go), but
Chemtronics make a kit to repair such keypads. Possibly worth it for
a useful instrument though.
In the UK you can get it here :

and I guess it's also available across the Pond.

So that's the answer: graphite powder. I now
have a working analyzer
again. It will be interesting to see if the graphite wears off
eventually, I suppose it might but that's ok, I can just do it again.
Many years ago I used graphite obtained from a soft pencil to revive
rubber keyboard pads and from my observation it wore rather quickly, in
particular moving to the surface contact was made against. I wonder if
there is a non-industrial way to make graphite stay in place on rubber.
