This standard 22/30405912 DC BS EN 17845. Construction products: Assessment of release of dangerous substances. Determination of biocide residues using LC-MS/MS is classified in these ICS categories:

• 91.100.01 Construction materials in general

This document describes a method for the determination of the content of biocides in construction products, (either finished (dried) or in a ready-to-use state) and in eluates thereof, using liquid chromatography and tandem mass spectrometric detection (LC-MS/MS). For content analysis liquid chromatography with UV-detection can also be used, if sufficient sensitivity and selectivity is ensured (see Annex A). The method in this document is validated for the product types listed in Annex D. For eluate analysis quantification limits of 0,1 µg/l can be achieved.
