Ultrasonic-assisted derivatization of estrogenic compounds in a cup horn booster and determination by GC-MS.


Cup horn boosters are miniaturized ultrasound baths that maximize efficiency and precision. The optimization of an ultrasonic-assisted derivatization step by means of a cup horn booster and the determination of estrone, 17beta-estradiol, estriol, 17alpha-ethynyl estradiol and mestranol was developed by GC-MS. Different derivatization reagents and solvents… (More)
