Silgur unmodified standard silica layers with concentrating zone

Glass plates. Silica 60, specific surface (BET) ~ 500 m²/g, mean pore size 60 Ä, specific pore volume 0.75 ml/g.

Kieselguhr zone for rapid sample application: because kieselguhr is completely inert towards a large number of compounds, the samples always from a narrow band at the interface of the two adsorbents, irrespective of shape, size or position of the spots in the concentrating zone. Separation then takes place in
the silica layer.

Available as glass plates with or without fluorescent indicator (UV254).
