DB-1ms GC Columns
Agilent J&W DB-1ms is a nonpolar, low bleed column, with excellent inertness for acids and bases and an extended upper temperature limit. Using low bleed stationary phases in DB-1ms reduces column contribution to background noise, resulting in a higher signal-to-noise ratio and better sensitivity. DB-1ms is bonded and cross-linked. In addition, reduced bleed results in improved mass-spectral purity and accurate library identification. The inertness of DB-1ms provides maximum response for active analytes commonly found in drug screening and environmental analyses.- 100% Dimethylpolysiloxane
- Identical selectivity to DB-1
- 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 and cross-linked; solvent rinsable
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 GC Columns
Agilent J&W DB-1ms Ultra Inert delivers consistent column inertness performance to ensure sensitivity, performance, and integrity. With excellent peak shapes, exceptionally low bleed and high signal-to-noise ratios, DB-1ms Ultra Inert performs effectively with even the most challenging active analytes. DB-1ms is also individually tested with Ultra Inert 1ms test probe mixture for peace of mind. An inert GC flow path further enhances performance.- Individually tested with Ultra Inert 1ms test probe mixture
