Construction products: Assessment of release of dangerous substances. Digestion by aqua regia for subsequent analysis of inorganic substances
This document specifies methods for obtaining the aqua regia digestible content of construction products.
Solutions produced by this method are for analysis by inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled spectrometry (ICP-OES) for the following 67 elements:
Solutions produced by the methods are suitable for analysis by cold vapour atomic absorption or fluorescent spectrometry (CV-AAS, CV-AFS), for mercury (Hg).
The method in this document is applicable to construction products. Digestion with aqua regia will not necessarily accomplish total decomposition of the sample. The extracted analyte concentrations might not necessarily reflect the total content in the sample.
NOTE Construction products include e.g.
