Specifications: Type C Silica Products for HPLC

Specifications - 4µm Silica

Silica: Spherical Shaped, Thermally Treated Type C Silica™; washed with Acid for low metals content,
< 10ppm.

ADVANTAGES:
Better Lot to Lot Consistency, More uniform bonding with Silicon-Carbon bonds, isocratic mobile phases more effective, less need for mobile phase additives. Highly stable in pH extremes, high temperature resistant and extremely low silanol activity. Maximum pressure for the columns should not exceed 4,500 psi during the run. Never remove any HPLC instrument while it is under any pressure to avoid damage to it.
