High performance capillary columns for gas chromatography (GC). This polysiloxane phase with autoselectivity meets USP G49. It 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 5 to the mid-polar OPTIMA 1701. Unique from MN, no similar phase. Ideal for nitrogen phosphorus (NP/PN) and MS detectors.
