- Abstract:
- The speciation of arsenic (As) in red wines has been developed and validated by HPLC – ICP MS. Four species were addressed, namely As(III), As(V), DMA and MMA. They could be determined at the (sub) µg As/L level depending on the species with repeatability, reproducibility and accuracy parameters consistent with the use of the method for discrimination studies. The method developed has then been applied to red wines from different origins. The results of Principle Component Analysis clearly show that even if As speciation does not allow a complete discrimination of the red wines as a function of the geographical origin, it is much more discriminant that the single total As determination.
