  • Rxi®-5Sil MS Columns

    Restek

    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 characteristics assures Rxi® columns…

  • Straight/SPME Inlet Liners for Agilent GCs

    Restek

    For Agilent GCs equipped with split/splitless inlets Geometry: Straight/SPME Liner ID: 0.75 mm Length: 78.5 mm OD: 6.35 mm Deactivation: Intermediate Polarity (IP) Material: Borosilicate Glass

  • Ultra Aromax Columns

    Restek

    Particle size: 3 μm or 5 μm, spherical Pore size: 100 Å Carbon load: 17% End-cap: yes pH range: 2.5 to 8 Temperature limit: 80 °C USP phase code: L11 Phase category: phenyl Ligand type: proprietary phenyl ligand

  • Rxi®-5ms Columns

    Restek

    Low-polarity phase; Crossbond® diphenyl dimethyl polysiloxane General-purpose columns for semivolatiles, phenols, amines, residual solvents, drugs of abuse, pesticides, PCB congeners (e.g., Aroclor mixes), solvent impurities Most inert column on the market Tested and guaranteed…

  • Rtx®-225 Columns

    Restek

    The cyanopropyl-containing Rtx®-225 phase is slightly less polar than bonded polyethylene glycol (PEG) phases, but it can be used for many of the same applications. Improvements to the Rtx®-225 polymer have increased thermal stability, reduced bleed, and improved inertness. The…

  • Rtx-200 GC Columns

    Restek

    midpolarity phase; Crossbond trifluoropropylmethyl polysiloxane General-purpose columns for solvents, Freon fluorocarbons, alcohols, ketones, silanes, glycols, and drugs of abuse. Excellent confirmation column with an Rtx-5 column for phenols, nitrosamines, organochlorine pesticides,…

  • Rtx®-OPPesticides2 Columns

    Restek

    Using sophisticated computer modeling software, we created two stationary phases for separating the 53 organophosphorus pesticides (OPP) listed in EPA Method 8141. Separation is improved and analysis time is significantly reduced, compared to other columns. The extended upper temperature limit of…

  • Mini Wool Puller/Inserter

    Restek

    Insert and remove wool plugs easily. Order a spare pack so you’ll always have one available.

  • Stx®-CLPesticides Columns

    Restek

    Many laboratories analyzing organochlorine pesticides struggle with breakdown and adsorption of endrin, DDT, and methoxychlor caused by active sites throughout the analytical system. Siltek® passivation technology enables these columns to offer unsurpassed inertness and the highest responses…

  • MXT®-5 Columns

    Restek

    The diphenyl dimethyl polysiloxane stationary phase is the most popular GC stationary phase and is used in a wide variety of applications. All residual catalysts and low molecular weight fragments are removed from the MXT®-5 polymer, providing a tight monomodal distribution and extremely low…

  • Rtx®-OPPesticides Columns

    Restek

    Using sophisticated computer modeling software, we created two stationary phases for separating the 53 organophosphorus pesticides (OPP) listed in EPA Method 8141. Separation is improved and analysis time is significantly reduced, compared to other columns. The extended upper temperature limit of…

  • MXT®-500 SimDist Column

    Restek

    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 SimDist…

  • Rtx®-1701 Columns

    Restek

    Rtx®-1701 is one of the more popular stationary phases used in capillary GC. The mix of cyano and phenyl functional groups increases the polarity and offers a different elution order relative to less polar Rtx®-1 or Rtx®-5 columns. An Rtx®-1701 column is ideal for confirmation…
