P. Michelsen et G. Pettersson, AN AUTOMATED LIQUID-CHROMATOGRAPHY MASS-SPECTROMETRY SYSTEM COUPLED ONLINE WITH MICRODIALYSIS FOR THE IN-VIVO ANALYSIS OF CONTRAST AGENTS, Rapid communications in mass spectrometry, 8(7), 1994, pp. 517-520
An automated high-performance liquid chromatography (HPLC)/mass spectr
ometry instrument coupled on-line with a microdialysis probe is descri
bed for the analysis of contrast agents in biological fluids. This sys
tem is used for pharmacokinetic and structure elucidation studies of c
ontrast agents used in X-ray and magnetic resonance imaging investigat
ions. Additionally an LC/MS system for the direct analysis of urine, t
hat obviates the need for conventional sample clean-up, is described.
