ZORBAX PSM High Performance Gel Permeation Columns

ZORBAX PSM columns are manufactured using rugged ZORBAX SIL porous silica microspheres (PSM) and can be used for molecular size separations on most synthetic and natural polymers. The packings have high mechanical strength and are not swelled or dissolved by any common organic or aqueous (pH 2-7) mobile phases. Zorbax PSM columns are available in two versions. The deactivated version has been silanized for use with non-polar or relatively polar polymers in nonaqueous or partially aqueous solvents, and is denoted by an S following the column name. The untreated version is for use with both nonaqueous and aqueous phases.
