  • HP-FFAP

    Agilent Technologies

    GC capillary columns are typically wound on 7 inch cages that fit into standard-sized GCs like the 6890. The 6850 GC has a smaller oven which requires the use of columns wound on a smaller cage diameter. Nitroterephthalic acid modified polyethylene glycol High polarity Temperature…

  • Retention gaps

    MACHEREY-NAGEL

    The retention gap technique in combination with on-column injection allows concentration of a large sample volume in the capillary column. Choice of the retention gap depends on the solvent used: the flooded zone after injection should be between 20–30 cm/µL Me-Sil retention…

  • nonpolar phase Manufactured from Siltek treated stainless steel tubing, MXT columns are the most durable high temperature GC columns available. As outlined in ASTM Method D6352, high temperature simulated distillation requires a column that can withstand temperatures to 430°C. MXT-1HT…

  • Capillary Column Ferrules

    Agilent Technologies

    Capillary ferrules are packaged in dial packs which deliver one ferrule at a time, keeping the others clean and ready for use. The dial packaging has been tested to ensure no out gassing of contaminants, including phthalates. *These ferrules are recommended for use with Agilent GC/MS…

  • SCOT column is a support-coated open tubular column prepared by a special process.

  • polar phase; Crossbond acid-deactivated Carbowax polyethylene glycol—for acidic compounds Stabilwax-DA bonded polyethylene glycol has an acidic functionality incorporated into the polymer structure. This permits analysis of acidic compounds without derivatization, significantly reduces…

  • low-polarity phase; Crossbond diphenyl dimethyl polysiloxane General purpose columns for drugs, solvent impurities, pesticides, hydrocarbons, PCB congeners (e.g., Aroclor mixes), essential oils, semivolatiles. Column specifically tested for low-bleed performance. Temperature range:…

  • low- to midpolarity phase Many analysts feel the Rtx-1301 column has the best cyanosiloxane bonded stationary phase available, with no other column manufacturer providing lower bleed, longer lifetime, or better inertness. Our polymer is fully characterized to ensure long-term reproducibility,…

  • nonpolar phase; dimethyl polysiloxane Rxi fused silica capillary GC columns were designed specifically to be the best columns available, for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In addition to outstanding performance, this combination of column…

  • OPTIMA® 5 Capillary columns for GC Features 5 % phenyl – 95 % methylpolysiloxane · USP G27, G36 Nonpolar standard phase with large range of application Low bleed columns with equal selectivity see OPTIMA® 5 MS, ultra low bleed columns see OPTIMA® 5 MS…

  • OPTIMA® 1701 MS Capillary columns for GC Features Silarylene phase with selectivity analog to 14 % cyanopropyl-phenyl – 86 % dimethylpolysiloxane USP G46 Mid-polar phase with very low bleed 100 % ion trap and quadrupol MS compatibility Reference column for…

  • Column bleed, measured by ECD, is extremely low at temperatures up to 330°C, which is critical for baking-out the column to remove high-boiling compounds commonly found in pesticide/PCB extracts. An analysis time of less than 10 minutes improves throughput compared to other stationary phases. …

  • SCOT column is a support-coated open tubular column prepared by a special process.

  • Your chromatography analysis does not end with the selection of the GC column. The combination of components selected for your instrument also make an important contribution to successful separations. Choose SGE technology to improve your chromatography.
