Description
  • High quality spherical porous silica gel
  • Normal-phase separation due to surface silanol groups
  • Two different pore sizes are available
  • Useful for separation of compounds with similar structures
  • YMC-Pack SIL is suitable for separation of fat-soluable compounds using non-polar mobile phase and separation of positional isomers that are difficult to separate in reversed-phase mode. SIL-06 (pre Diameter 60A) has greater absorption properties than SIL-12 (pore diameter 120A) due to its larger specific surface area, and is generally useful for separating natural products with a low molecular weight. Although water or acetic acid can be used as an additive to the mobile phase, they are likely to bind to silanol. In consideration of separation reproducibility, it is preferable to have one column dedicated to the mbile phase containing water or acetic acid.
