Unique Ultra Inert Advantages

Like all Agilent J&W Ultra Inert GC columns, Agilent J&W DB-624UI GC columns give you the advantages of:

Ultra Inert deactivation and manufacturing: Agilent’s industry-leading manufacturing process – combined with optimized chemistries and design advancements – improve both inertness and trace-level sensitivity with proven column-to-column reproducibility. This is accomplished with no trade-offs in bleed or stationary phase selectivity. The industry’s most demanding test probe mixture: All Agilent J&W Ultra Inert GC columns are individually tested with some of the most probative active compounds that can be analyzed by GC – including acetic acid, butyric acid, pyridine, 1,2 propanediol, bromoform, and dimethyl-methylphosphonate – at low temperature (70 °C). This ensures excellent peak shape performance at low levels (5-10 ng on-column). And, proof of inertness performance is included in the individual performance summary sheet which comes with every column.
