Micro/Capillary: YMC-Pack SIL

High Purity, High Sample Recovery

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, which lowers sample recovery and may cause unusual peak shapes.

High Sample Loading, High Mechanical Stability

The totally porous nature of the silica found in YMC-Pack SIL columns 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 high chemical purity of YMC silica results in a particle structure exhibiting high mechanical strength.


YMC-Pack SIL: Features & Benefits

Base Material: Silica
Stationary Phase: Bare silica (USP L3)
Particle Size: 3µm, 5µm
Pore Size: 60Å, 120Å, 200Å, 300Å
Endcapping: No
pH Range: 2-7.5

Standard Normal-Phase Column

YMC-Pack Sil is suitable for separation of oil-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.

  • Choice of 60Å, 120Å, 200Å, or 300Å pore size packings
  • High mechanical stability
  • Ultra-high purity silica
