Silylation is the introduction of a(usually) substituted silyl group(R3Si–) to a molecule. Nearly all functional groups which present a problem in gas chromatogaphic separation(hydroxyl, carboxylic acid, amine, thiol, phosphate) can be derivatized by silylation reagents. It involves the replacement of an acidic hydrogen on the compound with an alkylsilyl group, for example, trimethylsilyl(–SiMe3). 3, record 1, English, - silylation

La chromatographie gaz-liquide des composés organiques n’est pas toujours directement réalisable pour des raisons variées telles que polarité des molécules, température d’ébullition trop élevée, interférences de substances dont les temps de rétention sont identiques ou très voisins, etc. Les transformations préalables en esters méthyliques des fonctions acides ou esters, l’acétylation des fonctions hydroxylées ou aminées comptent parmi les techniques d’application courante. La silylation (radical silyle : –SiH3) mérite également un développement particulier en raison de ses nombreuses applications. 3, record 1, French, - silylation
