Identification of basic drugs in urine by dual fused silica capillary column GC.

abstract：:This paper presents a case of fatal overdosage due to an accidental massive administration (750 mg instead of 170 mg) of cisplatin, an anticancer agent, to a 63-year-old patient suffering from lymphoma. Platinum was measured in various postmortem samples by means of inductively coupled plasma mass spectrometry. Heart ...
