Trace metals in some biological samples were measured by the discrete nebulization technique in inductively coupled plasma atomic emission spectrometry. The small spray chamber and the time-sharing background correction system were used for the rapid measurements. Small amounts of the samples were decomposed quickly in a sealed PTFE vessel in a microwave oven. The analytical results for Al, Cu, Fe, Mn and Zn agreed well with the certified values and also with those obtained by continuous nebulization.
