A novel method for rapid HPLC-ICP-MS analysis of oxaliplatin in human urine was developed implementing a stationary HPLC phase with a particle size of 1.8 A mu m. The method allowed a cycle time of < 1 min at a HPLC flow rate of 0.9 mL min(-1). Procedural limits of detection of 0.05 A mu g L-1 oxaliplatin (150 fg on column) were obtained. Analysis of oxaliplatin in patient urine showed that accurate quantification of the intact drug demanded for storage at -80 A degrees C and rapid measurement after thawing.
