Further structure determination has been conducted by collisionally induced dissociation in a triple quadrupole tandem mass spectrometer. Overall, the electrospray ionization and tandem mass spectrometry methods prove to be simple, fast and sensitive for the analysis of anabolic steroids in urine samples.
