How to increase volatility? Is it possible to put a substance with low volatility into a highly volatile solvent, thus make the original substance also vaporize quickly?

If not, are there anyway to increase it's volatility?
The important thing is the solvent does not dissolve the substance. Then their vapour pressures sum up and they boil together.

This technique is massively used for obtaining aromatic oily essences from plants, that are mostly insoluble in water.

The destilate usually forms a stable emulsion, that gets extracted by lipophilic volatile solvent, that is later evaporated to got the substance, or a mixture of them.
