Collisional spectroscopy for unequivocal and rapid determination of morphine at ppb level in the hair of heroin addicts

A new analytical procedure for the identification of morphine in the hair of heroin addicts has been developed using collisional spectroscopy, on a commercially available, reverse geometry, double focusing instrument. Either collision-induced dissociation (B/E = const) linked scans or mass analysed ion kinetic energy spectra lead to an unequivocal and rapid determination of morphine in hydrolysed hair extract which may be compared with the data obtained by different and more traditional analytical methods.
