Quantification of chromium in whole blood has been performed by ICP-quadrupole MS. The spectrometer was equipped with a dynamic reaction cell (DRC) with ammonia as reaction gas. The rejection parameter q (RPq) of the DRC and the flow rate of ammonia (NH3) were optimized and set at 0.7 and 0.6 mL min(-1), respectively. Blood was diluted 1:51 (v/v) with an aqueous solution containing 0.1 mg L(-1) NH4OH, 0.1 g L(-1) EDTA, 5 mg L(-1) n-butanol, and 0.1 per thousand Triton X100. Non-spectral matrix effects observed when using the DRC were confirmed by use of vanadium. External calibration with blank and standard solutions prepared in purified water led to biased results for quality control samples. Standard addition calibration was therefore used and its validity verified. By comparing the slopes and calculating residues, it was proved that the plot obtained with standard additions and the plot obtained from blood samples of different concentrations were aligned down to 0.05 microg L(-1) after dilution.
