DB-UI8270D delivers excellent peak shape for trace-level analysis of active semivolatile organic compounds targeted by EPA method 8270D. Leading-edge manufacturing processes, combined with optimized chemistries and design advancements, improve both inertness and column-to-column reproducibility with no trade-offs in bleed or stationary phase selectivity. All DB-UI8270D Ultra Inert columns are individually tested with the most highly probative semivolatile compounds, including propanoic acid, pyridine, 1,2 butanediol, 1-chloro-2-fluorobenzene, and m/p xylene, at low temperature (45 °C), to ensure excellent peak shape performance at low levels (5 to 10 ng on-column). Features: • Specifically engineered for improved trace-level analysis of active semivolatile organic compounds • Industry-leading Ultra Inert deactivation and manufacturing • Unmatched testing protocol provides ultimate confidence in your results • “MS-Grade” low-bleed stationary phase ensures the lowest interference from the column at elevated temperatures • Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column
LTM column module. DB-1ms is a nonpolar, low-bleed column, with an extended upper temperature limit and excellent inertness for acids and bases. The low-bleed stationary phase reduces column contribution to background noise, resulting in a higher signal-to-noise ratio and better sensitivity for improved mass-spectral purity and accurate library identification. Features: • 100% Dimethylpolysiloxane • Identical selectivity to DB-1 • Nonpolar • Very low bleed characteristics, ideal for GC/MS • Improved acid performance compared to standard 100% dimethylpolysiloxane columns • Improved signal-to-noise ratio for better sensitivity and mass spectral integrity • Bonded, crosslinked, and solvent rinsable • Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column • Similar phases: SPB-1, Rtx-1, BP-1, OV-1, OV-101, 007-1(MS), SP-2100, SE-30, ZB-1, AT-1, MDN-1, ZB-1, ZB-1ms
DB-1ms Ultra Inert delivers consistent column inertness performance to ensure analytical sensitivity and integrity. With excellent peak shapes, exceptionally low bleed, and high signal-to-noise ratios, this column performs effectively with even the most challenging active analytes. Each column is individually tested with Ultra Inert 1ms test probe mixture.
