| Abstract: | GC-MS with negative ion chemical ionization has been used to detect anabolic estrogens (diethylstilbestrol, dienestrol, hexestrol, and 17β- and 17α-estradiol) in bovine muscle tissue. After hydrolysis and extraction, purification by column chromatography, and derivatization, the detection limit for the estrogens is better than 0.1 ppb. |
