GC column, Nonpolar–low polar, OPTIMA 5 Amine, 30 m L, 0.25 mm ID, 0.5 µm df 140-051-251 000 ppm single element solutionsHigh performance capillary columns for gas chromatography (GC). Especially deactivated GC phase (meets USP G27 G36) for the analysis of polyfunctional amines such as ethanolamines, amino functionalized diols and similar compounds, which are important base materials in industrial chemistry, and show strong tailing on standard deactivated columns Improved linearity for analyses of active components at trace levels no amine absorptions even for aliphatic
