Rapid determination of chlorobutanol in milk by glass capillary gas chromatography.
A rapid method for the determination of chlorobutanol(1,1,1-trichloro-2-methylpropan-2-ol) in milk is described. The method is based on a steam-distillation solvent-extraction technique and a quantitative determination of chlorobutanol by gas chromatography using a glass-capillary column coated with Carbowax 20M and 2,2,2-trichloroethanol as internal standard. The detection limit is 1 pg and recoveries of chlorobutanol are between 93 und 99%. Fifty-two milk samples have been analysed.
