CP-Sil 8 CB and CP-Sil 8 CB UltiMetal

Agilent J&W CP-Sil 8 CB incorporates 5% phenyl groups in the dimethylpolysiloxane polymer, and so it has a slightly higher polarity than CP-Sil 5 CB. This results in a better selectivity for aromatic compounds and is generally the best choice when developing a method. CP-Sil 8 CB shows excellent column-to-column reproducibility and very high column efficiencies. We recommend the UltiMetal column for the highest operating temperatures, and when working in rugged environments with process or portable instruments.
