Aluminium (Al) with ICP-AES
The sample is acidified with HNO3. The quantification is made by emission spectroscopy in a plasma instrument that measures all aluminium, except particles that are too large to vaporise in the plasma. In general, the values are slightly higher than for acid-soluble aluminium.
