2017 m. Nr. 2 An assessment of the in-house made stainless steel capillary GC column
To assess the performance of an in-house made stainless steel capillary column coated with a methyl polysiloxane stationary phase, demanding test mixtures containing benzene, n-octane, chlorobenzene, pentyl acetate, isopropylbenzene (cumene), benzenamine (aniline), 2-butanone, 1-hexanol and propionic acid have been suggested. The gas chromatographic analysis of the mixtures reveals that the column lacks inertness towards active analytes and can be used only for the analysis of the mixtures containing nonpolar compounds.
