Aerogel
A packing that can be prepared if the dispersing agent can be removed from a gel system without collapsing the gel structure. Silica gels and glass beads used for size-exclusion chromatography (SEC) are examples of aerogels, which can retain their structures even at the high pressures used in HPLC . | ||||

Aerogel
Aerogel is a low-density solid-state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties, most notably its effectiveness as an insulator. It is nicknamed frozen smoke, solid smoke or blue smoke due to its semi-transparent nature and the way light scatters in the material; however, it feels like expanded polystyrene (Styrofoam) to the touch.
