Which solvent, and why do you think that it would help?

 DCM with a 0.01 water content. Sparging may, with a heavier to air content, be useful in removing air or who knows if water. Because I will be making a cycle of sparging and vacuum.

Because I do not know your intended application, I will keep my comments very general.  If one needed dry DCM, my advice is to stick to literature methods involving molecular sieves or drying agents, for example calcium hydride.  If you need degassed DCM, I only have minimal experience in this area.
