Welch Materials Ultisil F-C8 Columns

Ultisil F-C8 is a fluorinated C8 reversed-phase column, where fluorine atoms replace hydrogen atoms on the RP stationary phase, containing a total of 17 fluorine atoms. It exhibits distinct selectivity from conventional C8 alkyl columns, offering strong retention for halogenated compounds and unique selectivity for non-halogenated polar compounds. It is an ideal choice when peak shape and separation performance on standard C8 columns are unsatisfactory.

Ultisil Series HPLC Columns are based on ultra-pure (purity > 99.999%) spherical and totally porous silica, unique bonding chemistry and proprietary surface modification techniques, producing excellent peak shape, column efficiency and exceptional lot-to-lot reproducibility. Ultisil column is the best choice for method development. owing to complete bonding chemistries and stable performance.

Features

Ultra-pure spherical porous silica, purity > 99.999%
Wide pH range: 2.0-8.0
High efficiency: theoretical plate > 80000/m
Excellent peak symmetry: tailing factor=0.95~1.05
Exceptional lot-to-lot reproducibility
