by Unimicro Technologies Inc.
Globalsil Si series of column packing used in a spherical porous and has a smooth surface of the ultra-pure silica gel, Al, Fe, Ti, Zi and other metal impurities content less than 10ppm, after careful and strict monitoring of the process of control production. Unique particle separation method to ensure that the precise particle size distribution. Under the same conditions, for different sizes of particles bonded end-capped, and thus obtain the same selectivity, retention time.
