Anion exchange chromatographic separation of polyfunctional compounds |
| abstract |
A weak anion exchange composition useful in polyfunctional compound chromatographic separations comprises an inert porous particle having a tetra-substituted silane material fixedly attached by covalent bonding to the surface thereof. A process for synthesizing the weak anion exchange composition is disclosed together with methods for separation of polyfunctional compounds and their isomers using a column packed with such weak anion exchange composition. |
