I have solutions of mercury, tms and various solvents and need to dry them. What is the best way of doing that?

Drying a solvent depends on the solvent usually.  Some solvents have to be treated, some will do just fine with molecular sieves.  Just out of curiosity, you have a solution of mercury that you need to dry?

I don't know if this will be helpful for your particular application, but here is a page that is a good resource on drying agents.

hey, there's an organic laboratory equipment called vacuum evaporator.
It evaporates the solvents with vacuum and heat.
But if one of these solvents is water, then it's a little more complicated.
Hope I helped you.
