GC column, Mid-polar–polar, OPTIMA DELTA-6, 30 m L, 0.25 mm ID, 0.25 µm df

High performance capillary columns for gas chromatography (GC). This polysiloxane phase with autoselectivity is a medium polar GC phase without CN groups. Autoselectivity (analytes determine the polarity of the phase) resulting in a polarity range from approximately the nonpolar OPTIMA 17 to the mid-polar OPTIMA 210. Unique from MN, no similar phase. Ideal for nitrogen phosphorus (NP/PN) and MS detectors.
