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.

Known issues with the parameter and/or important method changes

In general, the values analysed wiht ICP-AES slightly higher than for acid-soluble aluminium.

Aluminium can be analysed with several different methods. Read more in our method comparison "Aluminium analyserat vid institutionen för vatten och miljö - Jämförelse mellan olika metoder" (in Swedish).

Current method of measurement

The method was cancelled by the end of 2015. Samples taken from January 2016 are analysed with ICP-MS.
