The DS/EN ISO 22518 standard specifies gas chromatography, CG, for the determination of solvent content in water-reducible coatings. The standard is suitable for solvent analysis in water-reducible coatings such as Paints and varnish. Through gas chromatograph technology, the type and content of solvents in Coatings can be accurately determined, providing an effective quality control means for Coating producers and users. The method has high Sensitivity and accuracy, which can effectively separate and quantify complex solvent mixtures. This standard provides a reliable test method for environment monitoring and product safety assessment in the Coating industry to ensure that Coating products meet relevant health, safety and environmental requirements.
