Rapid screening of anabolic steroids in urine by reactive desorption electrospray ionization.


Fast screening for anabolic steroids in whole urine is achieved by combining reactive desorption electrospray ionization (reactive DESI) and tandem mass spectrometry. Spray solutions containing hydroxylamine allow heterogeneous reactions of hydroxylamine with the carbonyl group of the steroids during the ionization process. Seven steroids, including a… (More)
