  • Image of Rtx®-VMS Columns

    Restek

    Rtx®-VMS columns offer lower bleed, better selectivity, and overall faster analysis for separating volatile organic compounds, such as those listed in U.S. EPA Method 8260B. The Rtx®-VMS stationary phase is a highly stable polymer that provides outstanding analysis of volatile compounds, in...

  • Image of Rtx®-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 Rtx®-5 polymer, providing a tight mono-modal distribution and extremely low...

  • Image of Rtx-5Sil MS Columns

    Restek

    Engineered to be a low-bleed GC-MS column. Excellent inertness for active compounds. General-purpose columns—ideal for GC-MS analysis of semivolatiles, polycyclic aromatic compounds, chlorinated hydrocarbons, phthalates, phenols, amines, organochlorine pesticides, organophosphorus pesticides,...

  • Image of Resprep SPE Cartridges (Bonded Reversed Phases)

    Restek

    Hydrophobic (nonpolar) silica-based adsorbents; used to extract hydrophobic analytes from polar matrices, such as water (e.g., pesticides from water). All cartridges are manufactured using high density polypropylene and have polyethylene frits unless otherwise noted. Cartridges may be processed by...

  • Image of Rtx®-CLPesticides Column Kit

    Restek

    Improved resolution and faster analyses, compared to 1701 or phenyl phases, make these the pesticide columns of choice. Rtx®-CLPesticides columns are specially designed to overcome the coelutions and analyte breakdown typically encountered in chlorinated pesticide analyses for EPA Methods 8081,...
