Technology purifies organic materials


EAST HILLS, N.Y.—A proprietary membrane-based filtration module that removes contaminants and separates unwanted molecules in polymer and solvent solutions is designed to provide a more cost-effective and efficient method for purifying organic materials used in high-tech manufacturing.

NanoSep EL technology, developed by Pall Corp. (, is designed for compatibility with the most aggressive organic materials used for display, semiconductor and nanotechnology processes. Unlike conventional purification methods, which use chemical extraction techniques, the NanoSep EL system purifies organic materials via filtration.

Under development for four years, the polymer fractionation technology enables: classification of electric fluids based on molecular weights; concentration of electric fluids; and diafiltration purification of high-value materials.

Pall says its organic filtration technology can also be used for solvent recovery and re-use application, reducing expense and minimizing disposal costs.
