Magic Stationary Phase

Magic stationary phase, is a spherical, completely porous silica gel. The manufacturing process permits no performance-reducing micropores, but yields constant specific surface area.  Magic packing materials have very high purity and are free from metallic contaminants that could hinder optimum peak shape.  Bulk media is available for our complete line of Magic packing materials.

Parameters of Magic packing material include silica gel composition, hydrophobic strength, steric selectivity, peak symmetry for basic analytes, silanol capacity and ion exchange sites. These parameters are determined by procedures such as NMR and ICP in addition to chromatographic techniques.  This multiplicity of characteristics yields extremely reproducible carrier materials providing a basis for reliable, constant, batch-independent, high-performance separation columns.

Ultra-Pure Silica Gel

The silica gel utilized in the manufacturing process of Magic packing material is 99.999% pure silica gel.  A particle size distribution analyzer is used to test each batch for constant particle size.  Surface area, pore size and pore volume are determined by a BET analyzer.  AAS and ICP are utilized to test for metallic impurities.  The extremely low level of metallic impurities guarantees that no sample will be adsorbed and no complexes will be formed during chromatographic analysis.

Bonding and End-Capping

Efficient bonding and the elimination of harmful silanol group residues is monitored by NMR.  The absence of silanol group residues is shown by the excellent chromatographic performance with respect to basic and acidic analytes.

Halo

HALO C18 is a high-speed, high-performance liquid chromatography column based on a new Fused-Core^TM particle design. The Fused-Core particle provides a thin porous shell of high-purity silica surrounding a solid silica core. This particle design exhibits very high column efficiency due to the shallow diffusion paths in the 0.5-micron thick porous shell and the small overall particle size of 2.7-microns. The densely bonded, extensively endcapped dimethyloctadecyl stationary phase of HALO C18 provides a stable, reversed-phase packing that can be used for basic, acidic, or neutral compounds.  Halo material is manufactured by Advanced Materials Technology.   Bulk media is available for purchase through Michrom for Halo C18 and C8.
