Scope

This document specifies a method for the determination of elements in soil improvers or growing media extracts using inductively coupled plasmaatomic emission spectrometry (ICPAES) NOTE 1 Alternatively, other suitable analytical techniques, e.g. inductively coupled plasma mass spectrometry (ICPMS) or atomic absorption spectrometry (AAS), can be used for the measurement if the user proves that the method gives the same results. This method is applicable to aqua regia extracts prepared according to EN 13650:— 1. NOTE 2 The method may be used for the determination of other elements, provided the user has verified the applicability.
