Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Magnetic levitation</bold> (MagLev) provides a simple method for the separation of crystal polymorphs that differ in density (Δ<italic>ρ</italic>) 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 <italic>trans</italic>‐ cinnamic acid.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3h9k50wt" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
