ABSTRACT:
This disclosure describes a sample drying system and method that provides a high rates of evaporation and sublimation that is commonly employed in compound processing procedures. The drying increases the sample-solute concentration and removes the solvent completely to produce the dried sample as a non-volatile solute precipitate. Re-circulating of drying gas is disclosed along with a solvent cold trap.
