Agilent J&W DB-UI8270D deliver excellent peak shape for active semivolatile organic compounds targeted by EPA method 8270D, for environmental trace-level analysis with the utmost confidence. Agilent’s leading-edge manufacturing process, 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 – such as 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 of 5 to 10 ng on-column.
