Panele me bazë druri – Përcaktimi i melaminës së lirë pas nxjerrjes së saj nga materiali (ekstraktimi), duke përdorur kromatografinë e lëngshme me performancë të lartë (HPLC) me detektim ultraviolet (UV)

Wood-based panels - Determination of free melamine applying extraction and high-performance liquid chromatography (HPLC) with ultraviolet detection

Scope

This document specifies the determination of free melamine in coated and uncoated wood-based-panels.
NOTE 1 It is also applicable to other wood-based products, to other solid products e.g. impregnates or decorative paper and to liquid materials.
The determination of melamine is performed by extraction using dimethyl sulfoxide (DMSO) and subsequent high-performance liquid chromatography (HPLC) analysis and ultraviolet (UV) detection.
NOTE 2 For determination of melamine in foodstuff, EN 16858 is applicable. For determination of melamine in animal feeding stuffs, EN 17212 is applicable. For determination of melamine in textiles, EN ISO 1833-26 is applicable.
