Key Definitions â–¸
Ultra Inert (UI) Technology
Agilent’s specialized deactivation process that minimizes active sites within the column, ensuring improved recovery, reduced adsorption, and superior peak shapes for highly active or reactive analytes.
Ultra Inert 1ms Test Probe Mixture
A stringent QC mixture containing active and reactive compounds used to verify that each DB-1ms column meets Agilent’s Ultra Inert performance standards for peak shape, inertness, and analyte recovery.
Inertness
The resistance of a GC column’s surface to adsorb or react with analytes. Higher inertness results in better peak shapes, reduced compound loss, and greater sensitivity—especially for polar, acidic, or basic analytes.
Signal-to-Noise Ratio (S/N)
A measure of how clearly an analyte signal stands out from background noise. The low bleed and high inertness of DB-1ms columns improve S/N, enabling lower detection limits and higher-confidence quantitation.
0.18 mm Internal Diameter (ID)
A narrow-bore column format that supports higher carrier-gas linear velocities and faster analysis times, increasing sample throughput while maintaining resolution and efficiency.
Frequently Asked Questions â–¸
What makes DB-1ms Ultra Inert columns different from standard DB-1ms columns?
DB-1ms Ultra Inert columns undergo Agilent’s most advanced surface deactivation and are individually tested with the Ultra Inert 1ms probe mixture. This ensures the highest level of inertness, superior recovery of active analytes, and consistently low bleed for sensitive GC/MS analyses.
Why is inertness important for GC/MS workflows?
High inertness reduces adsorption and degradation of active or reactive compounds, producing sharper peaks, better signal-to-noise ratios, and more reliable quantitation—especially at low analyte concentrations.
What applications are DB-1ms Ultra Inert columns best suited for?
These columns excel in environmental analyses, forensics, petrochemical profiling, industrial QC, and any GC/MS workflow involving active, semi-volatile, or trace-level compounds requiring maximum inertness and low bleed.
Do DB-1ms Ultra Inert columns improve detection limits?
Yes. Ultra low bleed combined with enhanced inertness reduces MS background noise and improves signal clarity, resulting in lower detection limits and higher-quality mass spectra.
What documentation is included with each DB-1ms Ultra Inert column?
Each column ships with a Performance Summary that includes quality-control test results, chromatographic performance metrics, and confirmation of Ultra Inert certification.
