Description

High quality spherical porous silica gel.
The high-purity silica found in YMC-Pack SIL columns provides virtually complete sample recovery. The absence of silica impurities reduces non-specific sample adsorption, and the totally porous nature of the silica provides high sample loading. With some competitive silicas, the level of porosity would make the particles prone to fracture, resulting in fines and high backpressure. However, the elevated chemical purity of YMC silica results in a particle structure exhibiting high mechanical strength.
YMC-Pack SIL is suitable for separation of fat-soluble compounds using non-polar mobile phases, as well as the separation of positional isomers that are difficult to separate in reversed-phase mode. SIL-06 (60Å pore size) has greater adsorption properties than SIL (120Å pore size) due to its larger surface area, and is generally useful for separating natural products with low molecular weight.

Application Note

YMC-Pack SIL-06 is an unbonded, high-purity silica column for normal-phase HPLC separations. This configuration contains 5 µm spherical silica particles with 60 Å pores in a 4.6 × 250 mm analytical column. The polar silica surface supports adsorption-based selectivity with nonpolar or moderately polar mobile phases and is useful for separating compounds that show insufficient selectivity under reversed-phase conditions. Typical applications include steroids, tocopherols, fat-soluble vitamins, positional isomers, and low-molecular-weight natural products. The SIL-06 grade offers greater adsorption strength than some wider-pore bare-silica phases because of its comparatively high surface area. The recommended operating pH range is approximately 2–7.5, with an upper temperature limit of 50 °C.
