Using Magnetic Levitation to Separate Mixtures of Crystal Polymorphs

Magnetic levitation (MagLev) provides a simple method for the separation of crystal polymorphs that differ in density (Δρ) by greater than 0.001 g cm−3. Density-based separations of multiple crystalline forms were shown for four organic compounds: 5-methyl-2-[(2-nitro- phenyl)amino]-3-thiophenecarbonitrile, sulfathiazole, carbamazepine, and trans- cinnamic acid.
