•金属离子净化器3M™金属离子净化器旨在将高纯度溶剂系统中的金属离子降低至50ppt水平。Utilizing 3M's immobilized particle technology, which is comprised of either a strong acid cation exchange resin or a chelating ion exchange resin in a polyethylene matrix, 3M Metal Ion Purifiers provide effective, single pass reduction of metal ions from high purity resins and solvents, such as PGMEA, TMAH, BARC, and other lithography chemistries.
