Inertsil C8

Generally, silica based columns are mechanically stable and provide high efficiencies, however, they cannot be used under alkaline conditions and their residual silanol groups tend to adsorb organic bases.

InertSustain C8 is an octyl group (C8) bonded column delivering the same extreme inertness to any type of compounds just like InertSustain C18, which enables rapid analysis of highly hydrophobic compounds delivering symmetric peaks at a wide range of pH.

Benefits

• Newly Developed Evolved Surface Silica Gel
• Superior peak shape with better resolution
• Wide pH compatibility and high durability
• Strict quality control program results in high reproducibility
• Unmatched operating back pressure

The Most Deactivated C8 Column Ever Made

GL Sciences’ newly-developed chemical bonding technology allows Inertsil C8-4 to provide high efficiency and good peak shape where competitive columns fail. For example, in the example at right, Inertsil C8-4 is compared with competitive Octyl phases for the analysis of dextromethorphan, a basic compound. Where other columns show poor peak shape, often with secondary interactions that result in prolonged retention, Inertsil C8-4 delivers symmetric peaks with high efficiency.

Benefits

• Perfect End-capping technique
• Intensive elimination of trace metals has been acheevedon the silica gel surface
• Extreme durability to acidic mobile phase conditions
• High stability to 100% aqueous mobile phase conditions
