Wm. Moore et al., An improved capillary gas chromatography method for triethylamine. Application to sarafloxacin hydrochloride and GnRH residual solvents testing, ANAL LETTER, 32(13), 1999, pp. 2603-2612
A capillary gas chromatography (GC) method for residual solvents in the vet
erinary antibacterial compound sarafloxacin hydrochloride included triethyl
amine (TEA). Despite the use of commercially available deactivated columns
and inlet liners, the peak shape and reproducibility for the TEA peak were
very poor. The use of glass inlet liners and glass wool which were treated
with methanolic potassium hydroxide resulted in marked improvement for TEA.
This method was also used to determine residual TEA in the polypeptide GnR
