一般說明

Silica gel is a rigid 3D network of colloidal silica. It is exclusively used as a support material for the active titanium(III) centers in Ziegler-Natta catalysts. Silica gel allows a controlled fragmentation lresulting in the formation of uniform polymer particles with narrow particle size distribution and high bulk density. Silica gel is widely used as layer material for TLC. Plaster of Paris is generally used as binding agent to hold silica gel firmly to the TLC plates. Silica gel is used as sorbent which is applied to aluminium foils.
  • Outstanding wettability (even for 100% aqueous visualisation reagents)
  • Easy and precise cutting (no flaking of silica)
  • Excellent separation efficiency and reproducibility from batch to batch

應用

Silica gel on TLC Alu foils may be used to perform thin layer chromatography.
