| Abstract: | The optimization of the conditions of use of three commercial carbon-furnace atomic-absorption spectrometers for the determination of cadmium in urine is described. The performance of each instrument is evaluated with respect to sensitivity, precision, detection limit and accuracy. All three instruments could be used for the determination of cadmium at levels greater than 0.2 mug/l. in the urine of exposed and "normal" subjects. A sample can be analysed in duplicate in 15 min. No sample pretreatment is required. |
