Agilent DB-1ms

DB-1ms

◈ Product Information
The 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 reduces the column contribution to background noise resulting in a higher signal to noise ration and better sensitivity. In addition, reduced column 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.

► Point
• 100% Dimethylpolysiloxane
• Identical selectivity to DB-1
• Non-polar
• 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 340/360° upper temperature limit
• Bonded and cross-linked; solvent rinsable
