[Combined spectral analysis method to trace the chemical elemental composition of food].
We have applied the combined approach to the routine elemental analysis of food using the complex ICP AES + ICP-MS for both major and trace element groups. Matrix elements (up to 15-20), such as Na, Mg, Al, Si, P, K, Ca, Fe, Zn in biological samples can be determined by ICP-AES while the rest elements except of H, C, O, F, Cl measured by more powerful ICP-MS method, which is able to quantify up to 50-60 elements, depending on element/isotope abundances. The application of two methods provides more flexibility when working with unknown matrices and provides cross-checking to improve data reliability and also enhances sample throughput.
