Determination of macro and trace elements in multivitamin dietary supplements by high-resolution continuum source graphite furnace atomic absorption spectrometry with slurry sampling

- Three commercially available multivitamin dietary supplements were analyzed.
- High-resolution continuum source atomic absorption spectrometry was used.
- Analytical potential of graphite furnace atomization was evaluated.
- Slurry sampling technique was developed and optimized.
- Accuracy of the method was validated by analyses of certified reference materials.
