“…For this purpose, either alkylation by iodomethane or iodoethane in the presence of sodium hydride (acting as proton extracting agent) or acetylation by heptafluorobutyric anhydride were typically used (Bűchret & Løkke 1975;Karg 1993;Scott 1993;Gerecke et al 2001).…”

“…Caffeine, which does not suffer the derivatization reaction, was used as the internal standard only to correct errors of injection into the gas chromatography. [9,14,15]. It should be pointed out that the EPA has established a Lifetime Health Advisory (LHA) of 500 lg/L [20] for tebuthiuron in drinking water, a value much higher than the quantitation limit of 0.02 lg/L established in the present study.…”

“…L'extraction est suivie d'une dérivatisation par l'anhydre heptafluorobutyrique. Les dérivés formés présentent l'avantage d'être stables thermiquement, donc facilement analysables par chromatographie en phase gazeuse, et la sélectivité de la réaction permet de se dispenser d'une étape de purification (KARG, 1993).…”
