Leave the removal of metals from semiconductor materials to us! Metal removal filter for semiconductor chemicals.

Consideration for the stability of photo-chemicals in metal reduction! Achieving various levels of metal reduction! Added chelate type and non-ion exchange type purifiers.

In the chemical purification of ion exchange type purifiers, the risk of acid generation has remained a concern. These issues pose a risk of degrading the quality of chemically amplified resists. As the first phase, we announced Nylonpolar, a nylon-based membrane modified with functional groups that has a metal removal mechanism through liquid-liquid exchange. In the second phase, we developed and published a metal removal purifier that has a mechanism for metal removal through chelation and the immediate removal of acids generated by ion exchange. At Cobetter, we will continue to develop purifiers equipped with new perspectives on metal removal mechanisms to provide users with a wide range of solutions for metal removal. For those looking to apply new solutions to chemical purification, such as concerns about the inability to achieve effective metal reduction or the adverse effects of acid generation from ion exchange on chemical stability, this is a must-see. Finding a purifier that exhibits universal metal removal performance for all metals is a daunting task, but we strongly recommend having a wide range of solutions at your disposal. *For more details, please refer to the PDF materials or feel free to contact us.*
