High 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 and aromatic amines at concentrations of 100 pg/peak. Tested with the amine test mixture (REF 722317), which among others also contains diethanolamine and propanolpyridine (this test mixture is separately available). Similar phases: Rtx-5 Amine, PTA-5, CP-Sil 8 CB for amines.
