Significados de precipitated amorphous silica em inglês

The purification procedure entailed ethyl acetate extract, silica gel column, and thin layer chromatography.

The extracts were then further purified with SPE silica gel tubes deactivated with trimethylamine.

The dimer fraction was separated by size-exclusion chromatography (SEC) after pre-fractionation on silica gel.

After removing the template by calcination, porous dehydrated silica gel nanoshells of uniform size were obtained.

Both extracts were subjected to silica gel column chromatography for isolation of main constituents, followed by purification in sephadex.
