Total Silicon-HF


Total Silicon-HF



This method quantitatively determines the concentration of silicon utilizing a nitric acid/hydrogen peroxide/hydrofluoric acid microwave digestion and analysis by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The method has a detection limit of 0.01% and on homogeneous sample material is generally reproducible within 8% (relative).

Sample amount requested: 5 g (to allow for moisture determination)

Questions concerning limited sample size can be answered by the UC Davis Analytical Laboratory.
