“…Several methods, such as gas/liquid chromatography (GC/LC) detection 5 GC/LC-mass spectrometry detection 6,7 diode array detector (DAD) or DAD-mass spectrometry detection 8 and fluoroimmunoassay detection 2 have been reported for the determination of diethylstilbestrol. Although every method has its own advantages, most of the reported protocols are instrument-expensive, approach-complicated and timeconsuming.…”

The great inhibition of diethylstilbestrol to cobalt deuteroporphyrin catalyzed luminol-H2O2 chemiluminescence reaction, has been exploited to develop a novel and sensitive flow-injection chemiluminescence detection method for the determination of diethylstilbestrol. The optimum experimental conditions and the possible mechanism have been investigated. Under the optimized parameters, the relative chemiluminescence intensity is linearly related to the concentration of diethylstilbestrol in the range of 6 × 10 -10 -1.0 × 10 -8 g mL -1 and 1 × 10 -8 -1 × 10 -7 g mL -1 with a detection limit of 3.83 × 10 -10 g mL -1 . The proposed method could be successfully applied to the determination of diethylstilbestrol in pharmaceuticals.

In this study, a simple and efficient large volume injection gas chromatography-mass spectrometry (GC-MS) method, via a programmable-temperature vaporizer (PTV) inlet, has been developed and applied in the determination of estrogens in environmental water samples without a prior derivatization process. Three commonly used estrogens estrone, 17 beta-estradiol and 17 alpha-ethynylestradiol were selected as target compounds for this study. It has been demonstrated that the type of gas chromatograph liner and the initial inlet temperature can greatly affect the response intensity of estrogens. Three different types of PTV liners have been studied; the multibaffle liner generated the strongest response intensities towards the estrogen analytes. The results showed that the response intensities of estrogens reduced sharply while the initial inlet temperature increased. Various instrument conditions and sample preparation methods were studied in detail. The optimized method has been validated with good linearity, precision and accuracy. The method detection limit of each estrogen was found to be 0.041 ng/L for estrone, 0.046 ng/L for 17 beta-estradiol and 0.031 ng/L for 17 alpha-ethynylestradiol. To the best of our knowledge, these results represent the best sensitivities achieved for estrogens analyzed in water samples via traditional GC-MS method without a derivatization process. This method has been successfully applied in the analyses of different water samples.
