In comparison with the established Lewatit UltraPure 1296 MD mixed bed, the new UltraPure 1296 MD PLUS boasts a much lower content of metals such as iron, zinc and sodium. Early installations of the product as a final polishing filter in semiconductor manufacturing have yielded results close to the current analytical limits of detection.

Lanxess will be unveiling its new type of ion exchange resin to trade visitors at the UltraPure Micro conference being held in Austin, Texas from October 10-12, 2023.

‘The Lewatit UltraPure 1296 MD PLUS produced in Germany is a vital component for cost-effective, sustainable and fault-free manufacturing in the fast-growing international semiconductor industry,’ says Hans-Juergen Wedemeyer, Technical Marketing Manager at the Liquid Purification Technologies business unit at Lanxess.

Manufacturing semiconductors and displays requires complex water treatment for required purity. Modern wafers and microchips demand high-quality ion exchange resin systems. New analytical systems detect ions at low ppt and ppq levels. Achieving semiconductor performance involves up to 200 treatment steps, including demineralization, reverse osmosis, degasification, ultrafiltration, and hydrogen peroxide removal. The crucial final step relies on Lewatit UltraPure 1296 MD PLUS ion exchange resin.
