The BSI BS ISO 23322 standard specifies Gas chromatography, CG, for the determination of solvent content in coatings containing only organic solvents. This method uses gas chromatograph technology to qualitatively and quantitatively analyze organic solvents in coatings to accurately determine the type and content of solvents in coatings. This standard applies to all Coatings and varnish products containing only organic solvents and is important for ensuring Coatings formulation conformity, environmental compliance and performance testing. Gas chromatography, CG has high Sensitivity and high-precision, can provide reliable solvent content data, is a common analytical method in Coating production and quality control.
