My understanding of a 'monolith' is a vertical 'slice' of a soil profile, typically of the profile to a depth of 1 m, glued onto a backing material. Can that be what you are describing?

In case your SM is gel.. there is no need of solvent.

If crystal.. look for the setup in which UV-vis of solid/ porous material is possible (You may required to make a flat plate like sample)
