More than five decades of innovative phase technologies and unique fused silica production capabilities, together provide end-to-end separation solutions for all applications.

• 8% Phenyl Polycarborane-siloxane
• Preferred column for polychlorinated biphenyl (PCB) compounds
• Separates PCB’s on ortho ring substitution as well as boiling point
• Low bleed

For use with PCB congener analyses, nitro-substituted aromatics, polynuclear aromatic hydrocarbons and pesticides/herbicides.
