Semivolatiles Analysis Rxi®-5Sil MS Columns (fused silica) (low polarity Crossbond® silarylene phase; selectivity close to 5% phenyl/95% dimethyl arylene polysiloxane) • Engineered to be a low bleed GC/MS column. • Excellent inertness for active compounds. • General purpose columns—ideal for GC/MS analysis of polycyclic aromatic compounds, chlorinated hydrocarbons, phthalates, phenols, amines, organochlorine pesticides, organophosphorus pesticides, drugs, solvent impurities, and hydrocarbons. • Temperature range: -60 °C to 350 °C. The Rxi®-5Sil MS stationary phase incorporates phenyl groups in the polymer backbone. This improves thermal stability, reduces bleed, and makes the phase less prone to oxidation. Rxi®-5Sil MS columns are ideal for GC/MS applications requiring high sensitivity, including use in ion trap systems.

GC COLUMNS | APPLICATION-SPECIFIC COLUMNS Environmental restek innovation! • Very low bleed provides highest sensitivity. • Faster analysis time with full separation of chlorinated pesticides. Chlorinated Pesticides Analysis Rtx®-CLPesticides/Rtx®-CLPesticides2 (proprietary Crossbond® phases) • Application-specific columns for organochlorine pesticides and herbicides. • Low bleed—ideal for GC/ECD or GC/MS analyses. • Baseline separations in less than 10 minutes. • Stable to 340°C. CarboPrep® SPE Cartridges See page 393. 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, 608, and CLP. By achieving baseline resolution of the 20 target analytes, more accurate qualitative data can be obtained, providing reliable identification without GC/MS.
