GLC Determination of Ethopabate in Chicken Tissues by Derivative Formation
Keyword(s):
Abstract The published method for the determination of ethopabate residues in chicken tissues has been improved by formation of the 2,4- dinitrophenyl derivative of m-phenetidine, which is produced by hydrolysis of ethopabate. The derivative is suitable for gas-liquid chromatography, using an electron affinity detector, and allows a simpler cleanup procedure. The sensitivity of the method is about 0.05 ppm; average recoveries at 0.5 ppm range between 66 and 97% for all tissues.
