silicagel octadecil-silil, dezactivat pentru baze

Explanation:
http://www.umfcluj.ro/home/masterat-doctorat/Pocsai.pdf

For this reason, column manufacturers have created techniques for limiting the interaction of basic analytes with the surface silica.

grupele funcționale de pe suprafața silicagelului au un puternic caracter acid, ele “atrag” bazele și pentru a evita acest lucru se dezactivează aceste grupe

Peak tailing of some basic compounds can be eliminated by using base deactivated silica columns. These types of columns are made from silica which is fully hydroxylated and of ultra-high purity, which reduces the acidity of the silica. The result is less interaction of basic compounds with surface silanols and improved peak shape.

pentru simplitate cred că ai putea scrie simplu dezactivat, deocamdată nu găsesc o formulare mai elegantă

se pare că s-a tradus la fel și în franceză:

gel de silice octadécylsilylé pour chromatographie R (3 μm)(1),
désactivé pour les bases.
